Black/ Green PTFE/ FPM +EPDM Rubber Valve Seat for Butterfly Valve Seat
PTFE + EPDM compounded rubber valve seats produced by SML are widely used in textile, power station, petrochemical, heating and refrigeration, pharmaceutical, shipbuilding, metallurgy, light industry, environmental protection and other fields.
Product performance: high temperature resistance, good acid and alkali resistance and oil resistance; with good rebound resilience, sturdy and durable without leaking.
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.
Virgin PTFE (Polytetrafluoroethylene)
PTFE (Teflon) is a fluorocarbon based polymer and typically is the most chemically resistant of all plastics, while retaining excellent thermal and electrical insulation properties. PTFE also has a low coefficient of friction so it is ideal for many low torque applications.
This material is non-contaminating and accepted by the FDA for food applications. Although the mechanical properties of PTFE is low, comparing to other engineered plastics, its properties remain useful over a wide temperature range.
Temperature range: -38°C to +230°C.
Color: white
Torque adder: 0%

Constructed from a high-grade combination of PTFE and EPDM, our Stainless Steel Butterfly Valve PTFE Seat is engineered to provide unparalleled sealing efficiency and durability. The unique properties of PTFE, combined with the resilience of EPDM, make this valve seat capable of withstanding a wide range of media - from water and oil to gas, base oil, and even aggressive acids. This versatility ensures that our valve seats are the perfect solution for applications across various sectors, including but not limited to textile, power generation, petrochemical industries, heating and cooling systems, pharmaceuticals, shipbuilding, metal processing, light industry, and environmental protection. The valve seat is designed to fit seamlessly in butterfly valves ranging from DN50 to DN600 in port size, making it a suitable choice for both wafer and flange end connections. This adaptability, combined with the valve's high-temperature resistance, makes it an ideal choice for environments where high performance and reliability are non-negotiable. Moreover, the choice between a wafer-type centerline soft sealing butterfly valve and a lug type double half shaft butterfly valve without pin offers flexibility in application and installation. Highlighting its efficiency, the PTFE and EPDM compound not only ensures a tight seal but also enhances the valve's operational lifespan, reducing the need for frequent maintenance or replacements. Whether employed in the control of water, oil, gas, or any challenging medium, our Stainless Steel Butterfly Valve PTFE Seat represents the pinnacle of valve sealing technology, delivering unmatched performance and reliability.
