* Stainless Steel Bolts. * Precision molded in polypropylene. Polypro py lene is reinforced with fiber glass for additional strength. * Self-aligning ball moves freely against the PTFE seats for smooth operation. The valve opens and closes with very little pressure on the handle. * Ball is diamond turned, after molding, to make it spherically perfect, which provides precise contact between ball and seats. * FKM (viton type) seals. * PTFE self-lubricating stem bushings and seats cannot stick or bind. * Maximum operating pressure 100 P.S.I.
