Thermoplastic (Geon PVC, Corzan CPVC, Kynar PVDF, Natural Polypropylene) ball valves (size) are to have trunnion design, spherically machined ball, PTFE thrust bearing on steel reinforced actuating shaft, mounting lugs on outer body, PTFE seats pre-loaded with O-rings, and (Viton or EPDM) seals. One fitting shall be true-union type (threaded, socket, metric, etc.) and the other fitting shall be an adapter that threads directly to the ball valve and is (cemented, fused, butt-fused) directly to (size) piping component (tee, cross tee, etc.) so that ball valve is an intrinsic part of piping component. All valves are to be 100% individually tested prior to shipment. As manufactured by Plast-O-Matic Valves, Inc.
