SML rubber valve seat introduction:

• A butterfly valve seat is a type of flow control devise, typically used to regulate o fluid flowing through a section of pipe.
• Rubber Valve seats are used in Butterfly valves for sealing purpose. The material of the seat can be made from many different elastomers or polymers, including PTFE, NBR, EPDM, FKM/FPM, etc. 
• The Teflon (PTFE) liner overlays EPDM/ FKM 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/ FKM elastomer layer of the seat, which provides the resilience for sealing valve stems and the closed disc.
• Temperature range: -10°C to 150°C.
• OEM accepted.
