Introduction

Butterfly valves are essential components in various industrial applications, used to regulate flow. The choice of liner material significantly impacts the valve's performance, durability, and suitability for specific environments. EPDM+PTFE butterfly valve liners combine the properties of EPDM (Ethylene Propylene Diene Monomer) and PTFE (Polytetrafluoroethylene), offering a unique set of benefits for numerous applications.

Benefits of EPDM+PTFE Butterfly Valve Liners

EPDM+PTFE liners present several advantages, making them a popular choice in industries ranging from chemical processing to water treatment:

• Chemical Resistance: PTFE is known for its robust chemical resistance, making it suitable for handling aggressive and corrosive chemicals. EPDM enhances this property by providing excellent resistance to weathering, ozone, and aging.
• Temperature Tolerance: EPDM can withstand temperatures ranging from -40°C to 120°C, while PTFE can handle even higher temperatures up to 260°C, ensuring suitability across a wide range of thermal conditions.
• Flexibility and Elasticity: The flexibility provided by EPDM enhances the sealing capability of the valve, ensuring a tight shut-off, while PTFE contributes low friction and wear resistance.
• Low Permeability: The combination of EPDM and PTFE results in a liner with low permeability, reducing the likelihood of leaks and contamination.

Numerical Analysis

The performance benefits of EPDM+PTFE liners can be quantitatively assessed through various parameters:

• Chemical Resistance Index: EPDM+PTFE liners score a 9.5 out of 10 on standard chemical resistance tests, outperforming many traditional rubber and plastic liners.
• Operational Temperature Range: The combined material properties allow operational temperatures from -40°C to 260°C, providing versatility in application.
• Service Life: With a projected service life of over 15 years under normal operating conditions, EPDM+PTFE liners reduce the need for frequent replacements, lowering maintenance costs.
