About this file
This is a specification document for common requirements for process valves issued by Herbert, Rowland & Grubic, Inc. for the Skytop Lodge Sewage Treatment Plant Improvements Project (Project Number 005153.0436) in Pennsylvania. The specification establishes requirements for valves and valve actuators to be installed as part of the sewage treatment plant upgrades, which include an influent screening system, equalization tank, chemical feed system, two clarifier tanks, a post-aeration tank, and a UV disinfection system. The document references compliance with industry standards including AWWA, ASTM, MSS, NEMA, NFPA, and UL specifications. A pre-bid conference is scheduled for August 25, 2026 at 10:30 AM at the Skytop Lodge STP in Canadensis, Pennsylvania, with bids due by September 18, 2026 at 10:00 AM through PennBid. Bid security of not less than 10% in the form of a certified check or bid bond is required.
The specification requires valve manufacturers to have a minimum of three years of documented experience and mandates submittals including product data, valve-labeling schedules, manufacturer certificates, hydrostatic test results for valves larger than 12 inches, and installation instructions. Valves must be rated for maximum temperature and pressure conditions, feature counterclockwise opening and clockwise closing operations, and include appropriate directional markings. Gear-assisted manual actuators are limited to a maximum operating force of 60 pounds-force, with chain actuators required for shutoff valves mounted eight feet above the operating floor level. All valve actuators in hazardous locations must be UL-approved. Materials of construction for wetted parts must be compatible with the process liquid, and finishes must comply with AWWA C550 protective coating standards. Field quality control testing will be witnessed by the engineer and must demonstrate proper alignment and operation without excessive noise, vibration, or overheating.
