Product overview

Self-operated valve front pressure regulating valve is composed of valve body and balance spring and other components, without additional energy, using the medium's own pressure as the power source to introduce the actuator to promote the spring control valve core position, change the pressure difference and flow at both ends, so that the valve front pressure is stable, with sensitive action, good sealing, and small pressure set point fluctuation. It is widely used in the automatic control of gas, liquid and steam medium decompression and pressure regulation.
