Introduction

The PTFE+EPDM butterfly valve liner is an essential component in fluid control systems, providing critical sealing and corrosion resistance features. This article delves into its composition, functionality, and applications within various industries.

Understanding Butterfly Valves

Butterfly valves are quarter-turn rotational motion valves used to start, regulate, and stop fluid flow. They are lightweight, cost-effective, and designed for high-capacity situations.

PTFE+EPDM Liner Composition and Functionality

The PTFE+EPDM liner is a combination of Polytetrafluoroethylene (PTFE) and Ethylene Propylene Diene Monomer (EPDM). Each material brings unique properties:

• PTFE: Offers excellent chemical resistance, a low coefficient of friction, and high-temperature stability (up to 260°C).
• EPDM: Enhances flexibility, offers good resistance to weathering, ozone, and aging, and operates effectively within a temperature range of -40°C to 150°C.

Comparative Analysis of Lining Materials

The selection of valve liners depends on operational conditions. PTFE+EPDM liners outperform many traditional materials like nitrile or natural rubber in terms of chemical resistance and temperature stability. Here's a comparative table of popular lining materials:

Applications and Benefits of PTFE+EPDM Liners

PTFE+EPDM liners are widely utilized in industries requiring high chemical resistance, such as:

• Chemical Processing
• Food and Beverage
• Pharmaceutical

Key benefits include enhanced durability, reduced maintenance costs, and extended service life under harsh environmental conditions.
