- FKM (Viton type) seals
- Precision model polypropylene is reinforced with fibreglass for additional strength
- The self-aligning ball moves freely against the PTFE seats for smooth operation. The valve opens and closes with very little pressure on the handle.
- The ball is diamond turned, after moulding, to make it spherically perfect, which provides precise contact between ball and seats.
- PTFE self-lubricating stem bushings and seats cannot stick or bind
- Stainless steel bolts
