Introduction

Butterfly valves are critical components in various industries, designed to regulate the flow of fluids. The choice of liner material significantly impacts the valve's performance and durability. The combination of EPDM (Ethylene Propylene Diene Monomer) and PTFE (Polytetrafluoroethylene) as a liner material offers numerous advantages in enhancing the operational efficiency of butterfly valves.

EPDM+PTFE Liner Overview

EPDM is a synthetic rubber known for its excellent resistance to heat, weather, and aging, while PTFE, commonly known as Teflon, provides outstanding chemical resistance and low friction. When combined, these materials create a liner with superior sealing capabilities and longevity.

Benefits of EPDM+PTFE Liner in Butterfly Valves

The integration of EPDM+PTFE liners in butterfly valves presents several benefits:

• Chemical Resistance: PTFE offers high resistance to corrosive chemicals, extending the valve's life.
• Temperature Range: EPDM functions effectively in temperatures from -40°C to 120°C, while PTFE withstands up to 250°C, making the combination suitable for diverse applications.
• Low Friction: PTFE's low friction properties facilitate smooth valve operation and reduce wear.
• Sealing Efficiency: EPDM enhances sealing efficiency even under high pressure, reducing leak risks.

Performance Parameters

Quantitative analysis of EPDM+PTFE liners in butterfly valves reveals:

• Pressure Handling: EPDM+PTFE liners can handle pressures up to 16 bar (1.6 MPa) safely.
• Leakage Rate: The leakage rate is effectively minimized, conforming to ISO 5208 rate A standards.
• Durability: Lifecycle tests indicate a durability increase by 30% compared to traditional rubber liners.
