ZZVP self operated pressure regulating valve is a type of valve that does not require an external energy source. It uses the energy of the controlled medium itself as a power source, introduces it into the actuator chamber to generate thrust, and controls the movement of the throttling element to achieve automatic regulation. ZZYP regulating valve has comprehensive functions of measurement, execution, and control. Can be used in places without gas or electricity. Widely used in the automatic control systems of various equipment gas, liquid, and steam media in the petroleum, chemical, power station, light industry, and printing and dyeing industries for deceleration pressure, stabilization (used for post valve pressure regulation), and automatic control of pressure relief and stabilization (used for pre valve pressure regulation).
