The high-performance pneumatic cut-off (regulating) butterfly valve consists of a pneumatic piston actuator and an eccentric sealed butterfly valve. Pneumatic butterfly valves use valve positioners or solenoid valves to achieve continuous adjustment and positional control. The pneumatic actuator adopts reliable and efficient new single acting and double acting piston cylinders, enabling the valve to reach the specified position according to control requirements. This product has the advantages of lightweight and simple structure, high flow coefficient, easy operation and use, and long service life. It is widely used in automatic control systems of various industries for adjustment or positional control.
