The pneumatic Butterfly Valve consists of a pneumatic actuator and a butterfly valve body. The pneumatic actuator drives the opening and closing of the butterfly valve through compressed air. When compressed air enters the actuator, the air pressure drives the piston to rotate, thereby driving the valve stem and butterfly plate of the butterfly valve to rotate, realizing the opening or closing of the valve.
This valve has the characteristics of simple structure, flexible operation, and easy installation. It is widely used as an automatic control valve in pipelines in many industries, such as: petroleum, chemical, electric power, metallurgy, and water treatment.
▪Pneumatic butterfly valve using compressed air as the power source, the cylinder as the actuator, and with the help of electrical valve positioned, converter, solenoid valve and other accessories to drive the valve, to achieve switching volume or proportional adjustment, receive industrial automation control system control signals to complete the adjustment of pipeline medium flow, pressure, temperature and other process parameters.
▪Pneumatic butterfly valve is characterized by simple control, rapid response, and intrinsically safe, do not need to take additional explosion-proof measures.
▪Cylinder is made of aluminum alloy material, light weight, beautiful appearance.
▪The butterfly valves have simple structure, small dimensions, short structural length, small volume and light weight, which makes it suitable to be made of large diameter valves.
▪Suitable for installation on pipes with limited space, operating torque, labor saving.
