The movable diaphragm single seat regulating valve adopts a top guide structure and is equipped with a multi spring actuator. The regulating valve has the advantages of compact structure light weight sensitive action S-streamlined fluid channel small pressure drop loss large valve capacity flow characteristics and convenient disassembly and assembly. Pneumatic control valves are widely used to control gas liquid steam and other media and process parameters such as pressure flow rate temperature and liquid level are maintained at a given value. Especially suitable for working situations where the pressure difference between the front and rear of the valve is small and allows for small leakage.
