Premium Sanitary PTFE+EPDM Compounded Butterfly Valve Seat

Short Description:

PTFE+EPDM

The Teflon (PTFE) liner overlays EPDM which is bonded to a rigid phenolic ring on the outside seat perimeter. The PTFE extends over the seat faces and outsides flange seal diameter, completely covering the EPDM elastomer layer of the seat, which provides the resilience for sealing valve stems and the closed disc.

Temperature range: -10°C to 150°C.
