Butterfly Valve

Product Description

This product is a butterfly valve equipped with multi-spring pneumatic actuator, featuring light weight, small volume and stable output torque. Air source acts inside the actuator to overcome spring reaction force and drive the disc rotation to realize pipeline medium on-off regulation. When air supply pressure disappears, spring rebound resets the valve. The actuator can be divided into direct acting and reverse acting types according to action mode. With valve positioner, high-precision position adjustment can be realized. Equipped with manual operating mechanism, manual opening and closing can be performed on site in case of air source failure. Widely used in pipeline systems such as petroleum, chemical industry, electric power and metallurgy.
