Resilient Seated Concentric Butterfly Valve

Resilient seated concentric butterfly valves are widely used in low and medium pressure pipeline systems because of their compact design, reliable sealing performance, and cost-effective operation.

Compared with many traditional valve types, concentric butterfly valves provide:

  • Lightweight structure
  • Fast opening and closing
  • Low installation space requirements
  • Simple maintenance
  • Reliable shut-off performance

These valves are commonly used in:

  • Water treatment systems
  • HVAC systems
  • Industrial water pipelines
  • Fire protection systems
  • General industrial applications

FTK Valve provides resilient seated concentric butterfly valves designed for stable sealing performance and efficient industrial flow control.


What Is a Resilient Seated Concentric Butterfly Valve?

A resilient seated concentric butterfly valve is a quarter-turn valve that uses a centrally positioned disc and resilient soft seat to regulate or isolate fluid flow.

In concentric butterfly valves:

  • The valve stem passes through the centre of the disc
  • The disc rotates around the centreline of the valve seat

The resilient seat provides tight sealing between the disc and valve body.

Common seat materials include:

  • EPDM
  • NBR
  • PTFE

This valve design is widely used because of its:

  • Simple structure
  • Reliable sealing
  • Easy operation
  • Cost efficiency
