Features and Advantages
● The butterfly valve adopts a one-piece lug-type valve body with a soft valve seat design, making it heavy-duty and high-strength.
● The resilient soft valve seat isolates the valve body and valve stem from the pipeline medium, ensuring excellent sealing under rated pressure.
● Replaceable valve seat, easy to maintain, and long service life.
● The connection between the disc and the valve stem can be either with or without pins.
● High Cv value, low pressure loss, low torque.
● The operating mechanism can be a handle, worm gear drive, electric actuator, or pneumatic actuator.
