Summary of self-reliance type pressure regulator
ZZYP self-reliance type pressure regulating valve is a kind of no extra energy, use energy was charged with medium itself when power supply, introducing membrane chamber to generate thrust, to achieve automatic adjustment control throttle unit movement.Equipped with comprehensive survey, execution, control function.Can be in the place of no gas, no electricity.Widely used in petroleum, chemical, power, light industry, printing and dyeing industry automatic control system in a variety of gases, liquids and the reduction of steam medium pressure, voltage regulator (for valve pressure regulation) after pressure relief, voltage regulator (used in valve pressure regulation) automatic control.According to the different working conditions of the user can choose different valve core structure and different actuators, in order to achieve the best control effect.

After pressure closed type: used for valve pressure regulation, after the valve pressure, the valve closed, reduced pressure, in order to achieve the purpose of the voltage regulator.
Pressure: type used in valve after pressure adjustment, when the valve pressure, open the valve, pressure relief, in order to achieve the purpose of the voltage regulator.
