About Butterfly Valve

Butterfly valves are classified as "quarter-turn" valves. When the metal disk that's part of the valve’s design is rotated a quarter of a turn, it opens or closes. The disk, referred to as the "butterfly" is attached to a rod. When the butterfly valve is opened all the way, the disc rotates (a 1/4 turn), allowing for a nearly unrestricted passing of the fluid. You can also open the valve gradually to reduce flow. Turning the butterfly (disk), to close the valve, blocks the passage of the fluid. This is due to the disc always being perpendicular or parallel to the flow, resulting in a pressure decrease regardless of the position it is in.

Features

  • Operator flange conforms designed to work with manual, pneumatic or electric actuators.
  • The rubber seat is non-collapsible, stretch resistant, and blowout proof.
  • The precision machined disc ensures low operating torque and effective sealing up to 200 psi. The hydrodynamically designed disc allows for high capacity flow.
  • One piece shaft design ensures dependability and positive disc positioning.
  • Valves are epoxy coated for reducing good environmental effects.
