What is a compound butterfly valve seat?

Introduction

The performance of valves depends heavily on the quality and design of their seats. This article discusses the compound butterfly valve seat, a critical component in managing fluid flow and ensuring efficient valve operation.

What is a Compound Butterfly Valve Seat?

A compound butterfly valve seat is an integral part of butterfly valves, designed to provide a tight shut-off mechanism. It combines multiple materials to offer enhanced performance in terms of durability, chemical resistance, and flexibility.

Components and Design

Typically, compound butterfly valve seats are constructed using a combination of elastomers and fluoropolymers. The elastomer provides the necessary flexibility, while the fluoropolymer offers chemical resistance and a low coefficient of friction.

  • Material Composition: Often includes EPDM and PTFE, selected for their unique properties suitable for various industrial applications.
  • Design Specifications: These seats are custom-engineered to fit specific valve dimensions, with tensile strengths exceeding 15 MPa and elongation rates up to 300%.

Advantages of Compound Valve Seats

Compound valve seats provide numerous advantages:

  • Increased Longevity: Less susceptible to wear and tear, extending the valve's operational life.
  • Enhanced Seal Integrity: Offers superior sealing capabilities, reducing leakage rates to less than 0.01%.
  • Temperature and Pressure Resilience: Suitable for temperatures ranging from -40°C to 200°C and pressures up to PN25.

Industrial Applications

Given their resilience, compound butterfly valve seats find applications in various industries, including:

  • Chemical Processing: Handles aggressive chemicals without degrading.
  • Oil and Gas: Withstands high-pressure environments.
  • Water Treatment: Maintains integrity in harsh water conditions.
