ZZYP self-powered pressure regulating valve is a kind of pressure regulating valve without additional energy. It uses the energy of controlled medium itself as power source and introduces the actuating chamber to generate thrust, so as to control the movement of throttling element to achieve automatic regulation. ZZYP control valve has comprehensive functions of measurement, execution and control. It can be used in air-free and electricity-free places. It is widely used in the automatic control system of petroleum, chemical industry, power station, light industry, printing and dyeing industry for the deceleration of gas, liquid and steam media, pressure stabilization (used for pressure regulation after valve), pressure relief and pressure stabilization (used for pressure regulation before valve).
