Introduction

The PTFE EPDM butterfly valve liner is a significant component in modern industrial applications, particularly in fluid control systems. This article reviews its composition, properties, and the functional role it plays in ensuring optimal valve performance. We will also briefly analyze some standard products from Sansheng Fluorine Plastics company and their innovative solutions.

PTFE EPDM Butterfly Valve Liner

Composition and Properties

The PTFE (Polytetrafluoroethylene) EPDM (Ethylene Propylene Diene Monomer) butterfly valve liner combines the chemical resistance of PTFE with the flexibility and durability of EPDM. PTFE is renowned for its anti-corrosive properties and excellent thermal stability, tolerating temperatures ranging from -200°C to 260°C. EPDM adds resilience and flexibility to the liner, with high resistance to weather, ozone, and acids.

Functional Role in Valves

PTFE EPDM liners effectively seal the interior surfaces of butterfly valves. These liners prevent leakage, minimize friction, and extend the valve's operational life. The low friction coefficient of PTFE (0.05 to 0.20) facilitates smooth valve operation, which is critical in applications requiring precise flow regulation.

Numerical Analysis

Empirical testing shows that PTFE EPDM liners can withstand pressures up to 16 bar and are functional across various pH levels (ranging from 0-14). The longevity of these liners is evidenced by a 50% reduction in maintenance intervals compared to conventional elastomeric materials.
