Features and Advantages
● The butterfly valve uses a one-piece lug body with a soft valve seat design, built for heavy-duty and high strength.
● The valve disc uses spherical sealing, providing high sealing pressure and excellent sealing performance.
● The elastic soft valve seat isolates the valve body and stem from the pipeline medium and ensures excellent sealing under rated pressure.
● Replaceable valve seat, easy maintenance, long service life.
● The connection between the valve disc and stem can be either pinned or non-pinned.
● High Cv value, low pressure loss, low torque.
● The operating mechanism can be a handle, worm gear drive, electric actuator, or pneumatic actuator.
