Pneumatic Clamp Butterfly ValveIt is the preferred routine for pipelinesbutterfly valveIt has the advantages of simple structure, small flow resistance coefficient, flow characteristic tends to be straight, and will not retain debris. And light weight, easy to install, the advantages of driving torque is small.Pneumatic Butterfly ValveCan be used to cut off the medium, but also for regulating the flow of the medium. Widely used in drainage, sewage, food, heating, gas, ships, hydropower, metallurgy, energy systems and textile and other industries.

Product Features

  • Compact and lightweight, easy to disassemble and maintain, and can be installed in any position.
  • Simple and compact structure, low operating torque, quick opening with 90° rotation.
  • Flow characteristics tend to be straight, good regulation performance.
  • The connection between the butterfly plate and the valve stem adopts a pinless structure, overcoming possible internal leakage points.
  • The butterfly plate adopts spherical shape, which improves the sealing performance and prolongs the service life of the valve.
  • The seals are replaceable and reliable to achieve two-way sealing.
