SECTION IVa Page 2 of 36 Updated 12/18/2025

Team Insert Valve Specification The Ductile Iron 250 p.s.i.g. Insert Valve shall be a Resilient Wedge Gate Valve designed for use in potable water, reclaimed water, and backflow control systems. The design will allow the valve to be installed into an existing pressurized pipeline while maintaining constant pressure and service as usual. After closing the wedge and adequately restraining the valve body, the downstream pipe can be completely removed and replaced. The host pipe shall not be a permanent component of the InsertValve.

Ductile Iron Construction:

• The ductile iron body, bonnet and wedge provide strength and a pressure rating that meets or exceeds the requirements of AWWA C515. Insert Valve shall be ductile iron construction meeting

ASTM A536 Grade 65-45-12. Heavy-duty ductile iron construction for maximum toughness and strength.

• Chemical and modularity tests shall be performed as recommended by the Ductile iron Society, on a per ladle basis. Testing for tensile, yield and elongation shall be done in accordance with ASTM

E8.

• Sizes 12" and smaller must be capable of working on Cast/Grey Iron or Ductile Iron Class A, B, C and D, IPS PVC, C900 and C909 PVC, Steel, AC pipe diameters without changing either top or bottom portion of split valve body.

• 250 psig maximum working pressure. The pressure rating markings must be cast into the body of the insert valve.

• After the installation of the insert valve body on to the existing pipe, a pressure test of 1.1 times that of the contents shall be sustained for 15 minutes. Once the pressure test is effectively achieved, the insert valve body must not be moved in accordance with AWWA Standards. If the insert valve is moved, the pressure test must be completed again. The insert valve must not be moved or repositioned once the pressure test is achieved.

Resilient Wedge Gate Assembly:

• The construction of the Resilient Wedge shall comply with AWWA C509 requirements.

• The ductile iron wedge shall be fully encapsulated with EPDM rubber by a high pressure and high temperature compression or injection mold process. This will assure the ductile gate is fully coated with molded rubber – no exposed iron.

• The resilient wedge shall seat on the valve body and not the pipe to obtain the optimum seating and flow control results. The resilient wedge shall be totally independent of the carrier pipe.

• The resilient wedge shall not come into contact with the carrier pipe or depend on the carrier pipe to create a seal. Abrasion results, thus, shorting the life and quality of the shut down if the wedge contacts the pipe.

• Pressure equalization on the down or upstream side of the closed wedge shall not be necessary to open the valve.

SECTION IVa Page 3 of 36 Updated 12/18/2025

• The wedge shall be symmetrical and seal equally well with flow in either direction.

• The Resilient wedge must ride inside the body channels to maintain wedge alignment throughout its travel to achieve maximum fluid control regardless of high or low flow pressure or velocity.

• Oversized flow way. Unobstructed to provide optimum flow.

Fusion-Bonded Epoxy:

• The insert valve is fully epoxy coated on the interior and the exterior. The fusion-bonded coating is applied prior to assembly so that even the bolt holes and body-to-bonnet flange surfaces are fully epoxy coated.

• Valve shall be coated with a minimum of 8 mils epoxy in compliance with AWWA C550 and certified to ANSI/NSF-61.

Gaskets and Triple O-Ring Stem Seals:

• This insert valve features triple O-Ring stem seals. Two O-Rings are located above, and one O- Ring is located below the thrust collar.

• The lower two O-Rings provide a permanently sealed lubrication chamber that will make the valve easier to operate over a longer period of time. The upper O-Ring ensures that sand, dirt or grit cannot enter the valve to cause damage to the lower O-Rings. This is especially important for buried and sewage service applications.

• Side flange seals shall be of the O-Ring type of either round, oval, or rectangular cross- sectional shape.

Valve Stem & Thrust Washers:

• The gate valve stem and wedge nut shall be copper alloy in accordance with Section

4.4.5.1 of the AWWA C515 Standard.

• The non-rising stem (NRS) must have an integral thrust collar in accordance with Section 4.4.5.3 of AWWA C515 Standard. Two-piece stem collars are not acceptable. The wedge nut shall be independent of the wedge and held in place on three sides by the wedge to prevent possible misalignment.

• Two thrust washers are used. One is located above, and one is located below the stem thrust collar. Two thrust washers ensure easy operation at all times.

• NRS with AWWA standard turns.

• Operated by 2” square wrench nut according to ASTM A126 CL.B – open left.

SECTION IVa Page 4 of 36 Updated 12/18/2025

American Made Quality:

• All parts and components to be exclusively and completely assembled, manufactured, machined and coated in the USA.

• All physical and chemical test results shall be recorded such that they can be accessed via the identification number on the casting. These Material Traceability Records (MTR’s) are to be made available, in hard copy, to the purchaser that requests such documentation.

• All components shall be manufactured and assembled in the United States. The purchaser shall, with reasonable notice, have the right to plant visitation at his/her expense.

Hardware:

• Bolting materials shall develop the physical strength requirements of ASTM A307 with dimensions conforming to ANSI B18.2.1.

Extended Life Value:

• The stuffing box, operating stem and resilient wedge (complete bonnet and all moving parts) shall be removable, repairable and or replaceable under pressure. In other words, even while the valve is fully pressurized in the system all moving components can be removed under pressure. In the event the valve stem is broken or damaged, the bonnet can be removed under pressure.

• Internal pressure equalization system assures the safe entry and removal of the valve bonnet during initial installation as well as future maintenance. This alleviates the need for additional pipe penetration taps or foreign methods (i.e. compressed air or auxiliary water source) to equalize pressure.

Split Restraint Devices:

• Shall consist of multiple gripping wedges incorporated into a follower gland meeting the applicable requirements of ANSI/AWWA C110/A21.10.

• The devices shall have a working pressure rating of 350 psi for 4-12 inch. Ratings are for water pressure and must include a minimum safety factor of 2 to 1 in all sizes.

• Chemical and modularity tests shall be performed as recommended by the Ductile Iron Society, on a per ladle basis. Three test bars shall be incrementally poured per production shift as per U.L.

specifications and ASTM A536. Testing for tensile, yield and elongation shall be done in accordance with ASTM E8.

• Gland body wedges and wedge actuating components shall be cast from grade 65-45- 12 ductile iron material in accordance with ASTM A536.

• Mechanical joint restraint shall require conventional tools and installation procedures per AWWA

C600, while retaining full mechanical joint deflection during assembly as well as allowing joint deflection after assembly.

STS-03-B-4 EXECUTION

STS-03-B-4A PREPARATION

A. Underground Obstructions:

1. The Contractor shall fully acquaint himself with the related irrigation, paving, site grading, water supply, electrical supply and other utilities to preclude any misunderstanding and to facilitate a trouble-free installation. It shall be the responsibility of the Contractor to obtain all such information as it is made available.

Drawings and specifications of related work may be obtained from the Owner.

2. In the event that rock, underground construction work, utility lines or obstructions out of the ordinary are encountered in any plant pit excavation, alternative plant

SECTION IVa Page 24 of 36 Updated 12/18/2025 locations shall be selected by the Owner or the project Landscape Architect. Where locations cannot be changed and the obstructions may be removed or moved, the obstructions, shall be removed to a depth of not less than 3-feet below grade and no less than 6-inches below bottom of balls or roots when plant is properly set at the required grade.

B. Excavation of Planting Beds and/or Plant Holes: A minimum 12" of planting mixture for shrub beds and 6-8" planting mixture for ground cover beds is required.

1. Where excavation encounters materials which are unsuitable for plant growth, all of said unsuitable material shall be removed and replaced with planting mixture at the direction of the Owner’s representative.

2. The Contractor must verify that tree pits drain properly. If water within the tree pit does not completely percolate into the soil within 1 hour, a determination shall be made as to what will be required for necessary percolation.

3. In roadway bulbouts, all lime rock shall be removed, compacted base broken up, and lime rock replaced with topsoil.

4. Where excavation encounters materials which are suitable for plant growth, the plant hole excavations shall be roughly cylindrical in shape, with the sides approximately vertical with bottom of excavation slightly raised at center to provide proper drainage. Loosen hard subsoil in bottom of excavation.

5. For balled and burlapped (B&B) trees and shrubs, make excavations at least twice as wide as the ball diameter and equal to the ball depth, plus the following allowance for setting of ball on a layer of compacted backfill. Allow for 6-inch setting layer of planting soil mixture, or as detailed.

6. For container grown stock, excavate as specified for balled and burlapped stock, adjusted to size of container width and depth.

C. Plant Bed Preparation:

1. Inspection: Examine substrates and conditions under which products of this section are to be installed and verify that the work may properly commence. Do not proceed with the work until unsatisfactory conditions have been fully resolved.

2. Preparation of Planting Soil: Before mixing, clean topsoil of roots, plants, sods, stones, clay lumps, and other extraneous materials harmful or toxic to plant growth.

Mix specified soil amendments and fertilizers with topsoil to a minimum depth of

6-inches using a rototiller or similar equipment. Delay mixing of fertilizer if planting will not follow placing or planting soil within a few days.

STS-03-B-4B PLANTING

A. Time of Planting: Plant under favorable weather conditions. At option of and under full responsibility of the Contractor, planting operations may be conducted under unreasonable conditions without additional compensation.

B. Removal from Containers:

1. All containers shall be cut and opened fully, in a manner such as will not damage the root system.

2. Container grown plants shall not be removed from the container until immediately before planting, and with all due care to prevent damage to the root system.

C. Setting Trees:

1. Orientation: Place each plant in vertical position and rotate to obtain best visual appearance and proper relationship to nearby buildings or adjacent plants.

2. Root and Ball Preparation: Remove container from plants and lightly scarify roots in several places before placement. After placement, loosen binding from top and

SECTION IVa Page 25 of 36 Updated 12/18/2025 sides of balled and burlapped plants and remove box or platform and surplus bindings. Spread roots of bare root plants in natural manner and cut cleanly any that have been broken.

3. Root Crown to Grade Relationships: After settlement, root crown of plant shall remain about 2-inches above average finished grade with planting soil sloping away from trunk or stem and blending with finished grade.

4. Sloping Plant Beds for Positive Drainage: When plant beds are adjacent to buildings, curbs, pavement, or other water holding obstructions, grade bed before planting to create positive surface drains away from plants and buildings.

5. Placement: Set balled and burlapped stock on layer of compacted planting soil mixture, plumb and in center of pit or trench with top of ball at same elevation as adjacent finished landscape grades. When set, place additional backfill around base and eliminate voids and air pockets. When excavation is approximately two-thirds full, water thoroughly before placing remainder of backfill. Repeat watering until no more is absorbed. Water again after placing final layer of backfill.

6. The backfill shall be made with prepared planting mixture as specified hereinbefore and shall be firmly rodded and watered-in, so that not air pockets remain. The quantity of water applied immediately upon planting shall be sufficient to thoroughly moisten all of the backfilled earth. Plants shall be kept in a moistened condition for the duration of the planting period.

7. A water ring 6-inches in width shall be formed making a water collecting basin with an inside diameter equal to the diameter of the excavated hole. The water ring shall be maintained in an acceptable condition from the time of planting until the end of the required establishment period. The basin shall be level and, on steep slopes, shall be excavated in such a manner as will allow the base of the plant to be at approximate grade level.

D. Setting Groundcovers:

1. Shaping Bed: Finish grade per Drawings to required contours and provide positive surface drainage.

2. Spacing of Plants: Unless otherwise specified, center to center spacing of plants refers to planting bed surface plane, not a horizontal plane.

3. Root Preparation: Remove container plants and scarify roots in several places before placing in position. Spread roots of bare root plants in normal position.

4. Position of Plants: Place each plant to provide its best cover to ground; on steep slopes this may mean axis of plant is not vertical.

5. Crown to Grade Relationships: Place crown high enough so that plant will not be smothered by mulch. Slope planting mix upward form finished grade to meet crown.

6. Backfill and Watering: Fill over and around roots with planting soil mixture and firmly compact. Soak bed thoroughly with water soon after planting.

7. Dish Top of Backfill to Allow for Mulching: For spring planting, provide additional backfill berm around edge of excavations to form shallow saucer to collect water.

On slopes, provide berm only on downhill sides of excavation.

E. Staking and Guying of Trees: The Contractor is wholly responsible for the stability and plumb condition of all trees and shrubs. A method of the staking of trees have been provided on the Drawings and specified herein. If the Contractor would prefer to use an alternate method, he shall submit for approval procedures he will use for the maintaining the stability and plumb condition of all trees and palms.

1. Small Trees: For trees and shrubs of less than 1-inch caliper, the size of stakes and the method of tying shall be such as to rigidly support the staked plant against damage caused by wind action or other effects. These trees shall be staked with two

SECTION IVa Page 26 of 36 Updated 12/18/2025

2-inch wide stakes, set at least 24-inches in the ground and extending to the crown of the plant. The plant shall be firmly fastened to the stakes with two strands of

1½’’ synthetic strapping.

2. Large Trees: All trees larger than 1" caliper, other than palm trees, shall be guyed form at least three points with 1½’’ synthetic strapping. Guying shall be anchored to 2-inch by 4-inch stakes, 24-inches long, driven into the ground at least 2-feet and sufficient that the top of the stake is at least 3-inches below the finished ground level.

Each guy wire shall be clearly visible which mat require flagging with bright survey ribbon in three places 12" apart.

3. Palm Trees: Palms shall be braced with three 2-inch by 4-inch wood braces, toe-nailed to cleats which are securely banded at two points to the palm, at a point 1/3 the height of the trunk. The trunk shall be padded with five layers of burlap under the cleats. Braces shall be approximately 120 degrees apart and secured underground by 2-inch by 4-inch by 24-inch stake pads.

F. Pruning:

1. All broken or damaged roots shall be cut off smoothly and the Contractor shall prune, thin out and shape plants in accordance with standard horticulture practice.

2. Pruned trees shall retain required height and spread. Remove only injured or dead branches, unless otherwise directed by the Owner 's representative. Prune trees and shrubs to retain natural character and accomplish their use in the landscape design.

3. Remove and replace excessively pruned or misformed stock resulting from improper pruning.

G. Fertilizer: Fertilizer shall be applied at the following rates:

1. Trees: two (2) pound per inch of caliper if less than 6" D.B.H. or five (5) pounds per inch if over 6" D.B.H

2. Groundcovers: two (2) pounds per one hundred (100) sq. feet.

H. Mulch Placement:

1. Planting Beds: Place mulch to the required uniform depth soon after planting to prevent drying of planting soil around roots. When other operations such as top dressing or fertilizing do not necessitate delay, mulch promptly after planting; do not delay more than three days after plants have been set.

2. Mulch Types and Depths:

a. Trees and Shrubs: Heavy layer of wood mulch to a depth as shown on the plan details level with adjacent grades.

b. Groundcover: Provide depth as shown on plan details. Work into top of backfill and finish level with adjacent grades.

I. Watering: The Contractor shall continue watering for as long as is necessary to properly establish the new plantings. Care shall be taken to prevent staining of new construction where temporary well water is used.

J. Pest Control: Set up a good spray program to guard against scales, borers, foliar feeders, aphids, mites, leaf-spot and dieback, nematodes and canker-producing fungi.
