Features• FKM (viton type) seals.
• PTFE self-lubricating stem bushings and seats cannot stick or bind.
• Precision molded in polypropylene. Polypropylene is reinforced with fiberglass 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.
