I. Overview of ZZYP self-operated pressure regulating valve :
ZZYP regulating valve is a kind of valve that requires no external energy, uses the energy of the controlled medium itself as a power source, and introduces into the executive membrane chamber to generate thrust, and controls the movement of the throttle element to achieve automatic regulation. ZZYP control valve has comprehensive functions of measurement, execution and control. Can be used in airless and powerless places. Widely used in petroleum, chemical, power station, light industry, printing and dyeing industry departments in the automatic control system of various equipment gas, liquid and vapor medium pressure reduction, voltage stabilization (for pressure adjustment after the valve) pressure relief, pressure regulation (for the valve Front pressure adjustment) automatic control.
