Introduction

The function and efficiency of butterfly valves heavily depend on their components, among which the liner plays a critical role. Understanding the purpose, material specifications, and industry solutions surrounding the butterfly valve liner is pivotal for those involved in fluid control and management.

Purpose of a Butterfly Valve Liner

A butterfly valve liner serves multiple purposes. Primarily, it provides a tight seal against fluid leakage. Moreover, it acts as a protective barrier between the valve body and the processed fluid, which can be corrosive, thereby enhancing the valve's lifespan. The liner ensures optimal performance by reducing friction during the operation of the valve disc.

Material Analysis and Specifications

Butterfly valve liners are crafted from various materials tailored to specific operational needs:

• EPDM (Ethylene Propylene Diene Monomer): Excellent resistance to heat, ozone, and aging, with a maximum temperature limit of approximately 120°C.
• NBR (Nitrile Rubber): Highly resistant to oil and hydrocarbons, suitable for applications up to 100°C.
• PTFE (Polytetrafluoroethylene): Known for its non-reactivity and suitability in extreme temperatures reaching up to 230°C.

Choosing the correct liner material is essential, as it directly impacts the valve’s durability, safety, and compatibility with various fluids.
