What are the benefits of PTFE EPDM butterfly valve liners?

Introduction

PTFE EPDM butterfly valve liners are integral to various industrial applications, providing reliable sealing and performance in challenging environments. This article delineates the benefits associated with these liners, offering a comprehensive analysis of their material properties and applications.

Benefits of PTFE EPDM Butterfly Valve Liners

PTFE (Polytetrafluoroethylene) and EPDM (Ethylene Propylene Diene Monomer) rubber offer a unique combination of properties when used as liners in butterfly valves. These attributes impart the following benefits:

Chemical Resistance

PTFE is known for its exceptional chemical resistance, providing durability in environments that involve exposure to a variety of corrosive chemicals. EPDM complements this characteristic by offering resistance to acids, alkalis, and solvents, making the combination ideal for chemical processing industries.

Temperature Tolerance

PTFE exhibits a broad temperature tolerance ranging from -200°C to 260°C. This thermal stability ensures functionality in extreme temperature conditions. EPDM adds to this by offering thermal resistance up to 150°C.

Low Friction Coefficient

The intrinsic low friction coefficient of PTFE minimizes wear and tear, extending the lifecycle of the valve. This property significantly reduces maintenance costs and downtime.

Elasticity and Flexibility

EPDM's inherent elasticity allows for excellent flexibility and deformation recovery, making it suitable for valves that undergo frequent cycling operations.

Dimensional Stability

PTFE provides excellent dimensional stability under mechanical stress, ensuring reliable sealing performance over time. It maintains its shape and size even under high pressure.

Cost-Effectiveness

By combining PTFE and EPDM, industries can achieve cost-effective solutions without compromising on performance or durability, particularly in scenarios where both chemical resistance and flexibility are required.
