Introduction to EPDM+PTFE Butterfly Valve Seats

EPDM+PTFE butterfly valve seats are essential components in modern fluid control systems, offering a unique combination of materials that provide durability, flexibility, and resistance to various chemical and temperature conditions.

Working Principles of Butterfly Valve Seats

Butterfly valve seats operate by means of a rotating disk within the valve body, which aligns with the flow direction to allow or restrict the flow of fluids. The seat provides the sealing function necessary to prevent leaks when the valve is in the closed position.

Material Properties and Benefits

EPDM (Ethylene Propylene Diene Monomer)

• Temperature Range: -45°C to 150°C
• Excellent resistance to weathering, ozone, and UV exposure
• Good flexural properties and elasticity
• Compatibility with water, steam, and some chemicals

PTFE (Polytetrafluoroethylene)

• Temperature Range: -200°C to 260°C
• Exceptional chemical resistance, unaffected by virtually all chemicals
• Low friction coefficient, providing excellent non-stick properties
• High electrical resistance and thermal stability

Application Scenarios

EPDM+PTFE butterfly valve seats are widely used in industries such as water treatment, chemical processing, and food and beverage due to their ability to handle a variety of chemicals and temperature variations. Their sealing efficiency ensures minimal leakage, making them suitable for dynamic and critical applications.
