Introduction

Butterfly valves are critical components in various industrial applications. The choice of liner material can significantly affect the valve's performance, longevity, and suitability for specific applications. Combining Polytetrafluoroethylene (PTFE) and Ethylene Propylene Diene Monomer (EPDM) offers unique benefits. This article delves into the advantages of using a PTFE+EPDM liner in butterfly valves.

Benefits of PTFE+EPDM Butterfly Valve Liner

Chemical Resistance

PTFE provides excellent chemical resistance, making it suitable for handling aggressive media, including acids, alkalis, and solvents. EPDM enhances this resistance with its robust performance against a range of chemicals, offering dual protection.

Temperature Range

The PTFE+EPDM liner performs exceptionally well in a wide temperature range from -50°C to 150°C, making it adaptable for both low and high-temperature applications.

Elasticity and Flexibility

EPDM contributes to the liner's elasticity, allowing for excellent flexibility and resilience. This property helps in absorbing pipeline vibrations and adapting to slight misalignments.

Longevity and Maintenance

Due to the wear and chemical resistance of PTFE, combined with the durability of EPDM, this liner configuration offers an extended service life. Maintenance requirements are reduced due to its robust performance in varied environments.

Leak Tightness

PTFE's low friction coefficient and EPDM's sealing capabilities ensure superior leak tightness, crucial for maintaining system integrity and safety.

Numerical Analysis

The PTFE+EPDM liner shows a remarkable reduction in failure rates in harsh environments. Tests indicate a decrease in maintenance frequency by up to 40% and an increase in operational lifespan by approximately 30% compared to traditional liners.
