1 – UPPER STEM BUSHING: An upper stem bushing, retainer by a stainless steel ring, is provide 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 – BODY: Bodies are two piece wafer or lug style and are epoxy coated.All bodies meet full ASME Class150 or DIN 3840 flange drilling requirements (24” body is double flanged).
4 – BEARINGS: PTFE impregnated steel bearing provided for the precision alignment of the upper and lower stem.
5 – BLOWOUT PROOF STEM: A shoulder is machined into the upper stem. The stem and the disc are pressed together during assembly creating a positive stem to disc connection.
6 – PRIMARY SEAL: The primary seal is achieved by an interference fit between the extra wide disc hubs and contoured seat.
7 – SEAT DESIGN: The unique seat geometry lowers seating unseating toque while reducing wear on the contacting parts.
Direct Mounting As Per ISO 5211
