Pneumatic diaphragm control valve

Overview:

The pneumatic diaphragm control valve is a precise automatic control valve. It uses compressed air as the power source and, with the help of signals from related accessories such as electrical valve positioners, converters, solenoid valves, and position-holding valves, drives the valve body to move and changes the flow area between the valve core and the valve seat. So as to achieve the regulation of various process parameters such as flow rate, pressure and temperature of various fluids (such as gases, liquids and steam) in industrial processes.
