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, VITON, 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.
