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%
