Features and Advantages
● The butterfly valve adopts a one-piece lug body, compatible with various flanges, lightweight, and high strength.
● The resilient valve seat uses phenolic (or aluminum) hard backing to prevent movement and deformation to the greatest extent.
● The valve seat can be vulcanized, suitable for end-of-line piping and vacuum environments.
● The connection between the valve disc and valve stem is available in two types: a non-pinned spline type and a pinned type.
● High Cv value, low pressure loss, and low torque.
● The operating mechanism can be a handle, worm gear drive, electric actuator, or pneumatic actuator.
● Replaceable valve seat, easy maintenance, and long service life.
