Introduction to EPDM PTFE Butterfly Valve Liners
EPDM (Ethylene Propylene Diene Monomer) and PTFE (Polytetrafluoroethylene) are two materials known for their unique properties, which are combined to create efficient and durable butterfly valve liners. These liners are integral components designed to provide a tight seal and reliable operation in various industrial applications.
Benefits of EPDM PTFE Butterfly Valve Liners
Chemical Resistance
The combination of EPDM and PTFE in butterfly valve liners offers exceptional chemical resistance. EPDM provides resilience against polar substances like acids and alkalis, while PTFE is renowned for its non-reactive properties, resisting almost all chemicals at temperatures up to 260°C.
Temperature Performance
EPDM PTFE butterfly valve liners are designed to withstand extreme temperatures. EPDM functions well between -45°C and 120°C, whereas PTFE remains stable from -200°C to 260°C, making these liners ideal for both cryogenic and high-temperature applications.
Durability and Longevity
Combining EPDM's elastic properties with PTFE's durability results in a liner that can endure significant wear and tear. This enhances the lifespan of butterfly valves, reducing maintenance costs and downtime. Typically, these liners can last up to 25 years in appropriate conditions.
Friction Coefficient
PTFE has one of the lowest coefficients of friction of any solid, reducing operational friction and contributing to the energy efficiency of the valve. This low friction coefficient, often measured at 0.05 to 0.10, helps ensure smoother operation and less mechanical wear.
Flexibility and Compression Set
EPDM provides excellent flexibility, allowing the valve to maintain a tight seal even under variable pressure conditions. Its compression set is usually below 15%, which means it can return to its original thickness after being compressed, ensuring consistent performance.
