Features and Advantages
● The butterfly valve uses a one-piece square-hole universal flange body, suitable for various flanges, with high strength.
● The resilient valve seat uses phenolic (or aluminum) hard backing, maximizing resistance to movement and deformation.
● The valve seat can be vulcanized type, suitable for pipeline ends and vacuum environments.
● The connection between the valve disc and valve stem is available in both pinless spline type and pinned type.
● High Cv value, low pressure loss, and low torque.
● The actuator can be operated by a handle, worm gear drive, electric actuator, or pneumatic actuator.
● The valve seat is replaceable, easy to maintain, and has a long service life.
