THE NEW SERIES 44

A quantum advance in ball valve durability, cycle life, leak tightness and automation.

Flowserve Worcester Controls Series 44 three-piece ball valves, for many years the most respected ball valve design in the industry, are now better than ever. A major research, design, and testing program brings you a new valve, designed to ANSI B16.34 specifications with advanced seal technology and body mount bracket design. This means a very strong, tough valve that can handle pressure and unforseen piping strains with a stem seal that extends operational cycle life and a standardized overall design that keeps parts inventory to a minimum. Then there’s documentation. B16.34 means complete traceability of assembly and testing procedures, heat codes, and foundry identification. Full CMTRs (Certified Material Test Reports) on pressure vessel parts are optionally available. Valve identification is provided on a stainless steel nameplate meeting MSS SP-25.

High Performance An improved stem seal design, consisting of live-loaded PEEK and Polyfill® thrust bearings and seals, significantly increases valve cycle life over conventional ball valves and extends time between adjust-ments. In manual valves, the two spring washers are compressed by two retaining nuts. A single Nylon-insert locking nut and four spring washers are used on automated valves.

Body-Mounted Actuator Design Actuators for Worcester’s Series 44 three-piece valves are mounted on rigid, precisely machined, box-style brackets bolted to the valve center section. This brings a number of advantages to the valve user:

• Actuator loads are on the valve body;

• Actuators and brackets can be removed for service without affecting valve or piping integrity;

• Easy access for stem seal adjustment;

• Inventory simplification. Mounting brackets are common to three-piece and equivalent flanged valves.

MULTIPLE END CONNECTIONS, SEAT

AND SEAL COMBINATIONS

Available through a nationwide network of distributors, Flowserve Worcester Controls Series 44 quarter-turn ball valves and replacement parts are stocked and ready to be adapted to each individual application.

Features that make this tough, reliable ball valve so unique include tight shutoff, smooth two-way flow, advanced seat materials, a variety of interchangeable end connections, swing away three-piece construction, and a design ready for automation.

A variety of pipe ends, including socket weld, screw ends, butt weld or any combination of these, enables Series 44 valves to be adapted to fit standard and more unusual piping situations.

Series 44 (V67) valves can also be welded in place, fully assembled with “G” graphite-coated 316 stainless steel body seals and reinforced TFE, Polyfill, or High-per Fill® seats.

The range of Worcester’s seat materials is unmatched and includes Buna, Neoprene, TFE, Reinforced TFE, Polyfill, LubetalTM, High-per Fill and UHMWPE. These seats easily han-dle a great majority of industrial fluids with temperatures from -50°F to +600°F including steam, chemicals, petrochemicals, petroleum products, caustics and fluids containing solids, fibrous or abrasive materials.

SWING-OUT DESIGN FOR

EASY MAINTENANCE

The Series 44 is especially well suited for use in piping systems where line breaks are required and total entry into the line is necessary. The center section can swing out, eliminating the need to cut a valve out of line and having to replace both the valve and the pipe. Because of this design, the seats, seals and ball can all be replaced quickly and easily without disturb-ing pipe alignment. Acting as both a valve and a union, the Series 44 eliminates the need for a separate union.

TIGHT SHUTOFF AND

BIDIRECTIONAL SEALING

Worcester’s three-piece ball valves are designed to seal bidirectionally against resilient seats. Unique relief slots assist in downstream sealing and reduce torque. The ball is forced to the downstream side under pressure and forced against the downstream seat to effect and maintain a seal.

Consequently, the valve will give bubble-tight shutoff through-out a long service life even with seats of relatively non-resilient materials such as TFE or Polyfill. The seats are also designed to perform a wiping action during each cycle— cleaning foreign materials off both the seat and ball, assuring leak-tight sealing.

The downstream sealing of Worcester’s three-piece valves overcomes the two most common difficulties in the use of conventional ball valves: seat damage and high operating torque. A hole in the stem slot prevents any possibility of damage due to trapped cavity pressure when the ball is open.

An optional ball cavity vent is available for specific applications.

The Worcester design results in smoother, more efficient valve operation.

• For high-pressure applications to 3000 psi, Flowserve recommends the Series 4 three-piece valves with Lubetal seats. Refer to brochure WCABR1009. For pressures to 5000 psi, specify the Series H44 Dyn-O- Miser® valve with Lubetal or High-per Fill seats. Refer to brochure

WCABR1048.

CAUTION: For high pressure media that are highly flammable, explosive or toxic, consult Flowserve.

NOTE: Standard Worcester valves are assembled with silicon-based break-in lubricant. For other options, consult your distributor or Flowserve.

OPERATING TORQUE FOR

AUTOMATED VALVES

Valve Torque:

Before the actuator can be sized for any given valve application, the operating torque required for the valve must be determined. The oper-ating torque of the ball valve is influenced by a number of factors— some are design- and materials-related, others are application- (ser-vice conditions) related. Design-related factors include the type and material of the valve seats, while application factors include system pressure, media and frequency of operation.

For complete valve operating torque data, refer to Worcester’s Actuator Sizing Manual (ASM). This eight-page publication explains the concept of valve torque, presents torque curves for each seat material, and provides correction factors for media and the type of service such as on-off operation, cycle frequency, etc.
