Pneumatic fluorine-lined diaphragm control valve

Overview:

The pneumatic fluorine-lined 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, changing the flow area between the valve core and the valve seat, thereby achieving the regulation of various process parameters such as flow, pressure, and temperature of various fluids in industrial processes. The valve body and internal components are made of high-temperature molded fluorine-lined (such as F4, F46, PFA and other anti-corrosion materials), which can effectively resist the erosion of corrosive media. The product is widely used in occasions with strong corrosive liquid media such as acids and alkalis.
