Introduction

Butterfly valves are integral components in various industrial applications, providing efficient flow regulation. A critical element in enhancing the performance of these valves is the use of a PTFE (Polytetrafluoroethylene) liner. This article delves into the role of PTFE liners in butterfly valves, examining their technical specifications and subsequent benefits.

Purpose of PTFE Liner in Butterfly Valves

PTFE liners serve to enhance the chemical resistance, reduce friction, and improve the sealing performance of butterfly valves. Their core function is to ensure the valve operates efficiently even in harsh conditions, managing flow with precision and durability.

Technical Specifications

The integration of PTFE liners in butterfly valves is driven by specific technical parameters:

• Chemical Resistance: PTFE liner withstands up to 95% of corrosive chemicals at temperatures ranging from -200°C to 260°C.
• Friction Coefficient: PTFE has a low static and dynamic friction coefficient, typically 0.1-0.2.
• Pressure Ratings: PTFE lined butterfly valves accommodate pressure ratings often under 16 bar.

Benefits of PTFE Lined Butterfly Valves

Using PTFE liners in butterfly valves provides numerous advantages:

• Corrosion Resistance: Prevents chemical attack on the valve body and disc.
• Long Lifespan: Reduces wear and tear, extending operational life.
• Enhanced Sealing: The resilience of PTFE ensures tighter seals, minimizing leakage.
• Low Maintenance: Due to their durability, PTFE-lined valves require minimal maintenance.
