Features & Benefits

1 – UPPER STEM BUSHING: An upper stem bushing, retainer by a stainless steel ring, is provided to absorb actuator side thrusts and is acetal as standard or PTFE as an option.

2 – UPPPER STEM SEAL: Keeps environmental contaminants from entering the stem bore.

3 – BEARINGS: PTFE-impregnated steel bearing provided for the precision alignment of the upper and lower stem.

4 – PRIMARY SEAL: The primary seal is achieved by an interference fit between the extra wide disc hubs and the contoured seat.

5- SEAT DESIGN: The unique seat geometry lowers the seating unseating toque while reducing wear on the contacting parts
