Pneumatic Triple Eccentric Butterfly On Off Valve

Pneumatic triple eccentric butterfly on off valve consists of piston type pneumatic actuator and butterfly valve. The butterfly valve is flanged and adopts a triple eccentric structure. The sealing surface wears less during the opening and closing process, so the service life is long. The sealing surface material adopts metal hard seal, which is resistant to high temperature and wear resistance, and allows the sealing specific pressure to be high, which improves the working pressure of the butterfly valve.

Pneumatic actuators are equipped with accessories such as solenoid valves, limit switches, air filter regulators, etc., which can be used for switch control. It has fast opening and closing speed, good sealing, and has remote signal feedback, which is suitable for remote on-site automatic control. When adjustment and control are required, an electric valve positioner needs to be installed to receive the 4-20MA signal from the control system. The medium in the pipeline can be adjusted and controlled by rotating the angle of the butterfly plate proportionally. Pneumatic triple eccentric butterfly on off valve is widely used in chemical industry, water treatment, metallurgy and other industries.
