High Performance Butterfly Valve

High performance butterfly valve, or double eccentric butterfly valve, is widely used in water treatment, power plants, steel mills, chemical industries, and environmental engineering, particularly for flow regulation and shutoff in pipelines. Compared to concentric butterfly valves, they offer higher pressure resistance, longer lifespan, and greater stability. In large diameters, they are lighter and more cost-effective, but for sizes below DN200, increased flow resistance limits practicality. The double eccentric design offsets the valve stem from the disc and body centers, allowing the disc to quickly disengage from the seat. This reduces wear, lowers torque, extends seat life, and enables the use of metal seats for high-temperature applications.

Double Offset Butterfly Valve

The Double Offset High-Performance Butterfly Valve is a new type of butterfly valve designed by absorbing the advantages of several different structural butterfly valves. The sealing surface of the valve plate is a spherical arc surface. The sealing mechanism achieves a true dynamic seal through system pressure, thus providing reliable sealing performance and durability. It features a small volume, light weight, wide manufacturing range, and is easy to maintain and repair. Due to its double offset butterfly plate design and single-piece flexible lip-shaped sealing seat, it is ideal for applications requiring reliable sealing and good regulating characteristics. It can be used for quick shut-off or regulating flow.

Double Offset High-Performance Butterfly Valve Components

Double Offset Frictionless Design

  • 1st offset: Shaft is positioned downstream from the centerline of the seat.
  • 2nd offset: Shaft is off center from the vertical axis of the seat.
  • ISO 5211 Top Flange
  • In addition to standard, durable V-ring packing, you can also choose from optional graphite
  • high temperature packing or emissions control packing.
  • Bi-Directional, Shut off performance
  • Seat Options: Rubber, PTFE, RPTFE, or Fire Safe PTFE
  • The double offset operating principle minimizes seat wear and lowers operating torque to
  • improve durability.
  • Positive sealing is mechanically achieved and does not rely on line pressure assistance.

Seat Structure

Double Offset PTFE Seat Butterfly Valve

  • A surplus of material between the PTFE Seat and Disc ensures a reliable seal in a low pressure environment.
  • In high pressure situations, the force of the medium pushes against the seat contacting the sealing surface for a stronger seal.
  • The disc surface has a conical design to reduce frictional force. The valve seat can also be replaced or repaired easily.

Double Offset Fire Safe PTFE Butterfly Valve

  • Fire Safe valve seat with dual seal includes a primary PTFE seat insert and metal seat. 
  • In the event that the PTFE insert is destroyed, the secondary metal seat provides an effective shut-off. 

Shaft Retention

  • Externally retained, double blowout proof stem design as API 609
  • External: Shaft is designed with an integral collar and gland follower to prevent blowouts.

Zero Leakage

  • Disc-Seat sealing is achieved by evenly loading torque force onto the disc's laminated seal
