3-Way poly ball valves are precision molded from polypropylene that is reinforced with fiber glass for additional strength. The self-aligning ball moves freely against the PTFE seats for smooth operation. The ball is diamond turned, after molding, to make it spherically perfect, which provides precise contact between ball and seats. It has PTFE self-lubricating stem bushings and seats, FKM seals and stainless steel bolts. These valves have a maximum operating pressure 100 PSI. They are bottom load valves with directional flow, right or left. Valve can be turned off to stop flow.
