Our High Performance Butterfly Valves are designed to seal against full line pressure rating of the valve body. The valves are suited for on/off, or throttling service in high pressure or vacuum applications with gases, liquids, slurries, and semi-solid applications.

Flow

Valves are bi-directional and valve bodies are designed to distribute stress evenly.

Automation

Valves are easily automated with Hydraulic, Electric, or Pneumatic Actuators.

Disc

Eccentric disc design assures valve closing will contact disc to seat in only the closed position. Streamlined Disc design provides excellent flow control over a wide range of pressure drops.
