About this file
This document is a Technical Specification for Bid #26-08 for Plumbing Supplies for the Cedar Point Oyster Hatchery, solicited under RFX-3160007664. The specification details precise requirements for true union PVC/CPVC ball valves, with Spears Manufacturing Model 2000 Series specified as the primary product. The procurement involves multiple valve types and sizes, including 16 units of 3/4" PVC Union 2000 SOC EPDM, 9 units of 1" PVC Union 2000 SOC EPDM, 129 units of 2" PVC Union 2000 SOC EPDM, and various other valve configurations totaling approximately 800 individual valve components across different sizes and specifications.
The technical specification outlines rigorous requirements for valve materials, pressure ratings, design, and construction. Valves must be manufactured from PVC or CPVC, feature PTFE seats, EPDM O-rings, and comply with NSF/ANSI 61 for potable water use. They must be pressure-rated between 150-235 psi depending on size, incorporate specific design features like blowout-resistant stems and full port ball design, and be manufactured under an ISO 9001 certified quality management system. The specification is specifically tailored for an aquaculture facility environment, emphasizing corrosion resistance, chemical compatibility, and serviceability of the valves.

Bid# 26-08 Plumbing Supplies for the Cedar Point Oyster Hatchery
RFX- 3160007664
Technical Specification – True Union PVC/CPVC Ball Valves (“Spears or Equal”)
1. General Provide factory-manufactured, corrosion-resistant true-union thermoplastic ball valves suitable for use in pressurized water and compatible fluid systems. Valves shall be Spears Manufacturing Model 2000 Series or equal, meeting all performance and dimensional requirements specified herein.
2. Materials
• Valve body and end connectors shall be manufactured from PVC Type I, ASTM D1784, Cell Class 12454, or CPVC Type IV, ASTM D1784, Cell Class 23447.
• Seats shall be PTFE (Teflon®) or equivalent, providing low operating torque and chemical resistance.
• O-rings shall be EPDM (or Viton® if specified), suitable for potable water service.
3. Pressure Rating
• Valves shall be pressure-rated to 235 psi at 73°F for sizes ½″ through 2″, and 150 psi at 73°F for sizes 2½″ through 6″, for water and other non-shock fluids.
4. Design & Construction
• True Union Design: Union nuts shall allow removal of the valve body from the piping system without disturbing pipe connections.
• Union Nut Threads: Union nuts shall use buttress threads or equivalent heavy-duty design to prevent cross-threading and withstand high torque.
• Stem Design: Valves shall include a blowout-resistant stem design (e.g., Spears’ Safe-T-Shear® or equal) to maintain seal integrity if stem failure occurs.
• Seal Carrier / Blocking Feature: Valves shall incorporate a design that permits downstream union removal under system pressure without blowout (e.g., Spears’ Safe-T-Blocked® or equal).
• Ball Design: Valves shall be full port to minimize pressure drop and allow unrestricted flow.
• Serviceability: All internal components (ball, seats, O-rings, seals) shall be replaceable without removal of the valve body from the pipeline.
5. Standards & Certifications
