Self regulating valve, ZZYP self regulating valve

關(guān)注次數(shù)：

ZZYP self pressure regulating valve is a kind of without external energy, using controlled the media's own energy when the power source, is introduced to perform film chamber to produce thrust, throttle control element to achieve automatic adjustment. Comprehensive function ZZYP control valve has the measurement, implementation, control. Available in no gas, no electric place. Widely used in petroleum, chemical, power, light industry, printing and dyeing industry in the automatic control system of gas, liquid and various equipment steam medium pressure regulator (for deceleration, pressure regulating valve after the pressure relief, pressure) (for the valve before the pressure adjustment automatic control).
