Self-operated Pressure Regulating Valve Introduction:

ZZYP self-acting pressure regulating valve is a need without external energy, the use of the controlled medium itself as a power source, the introduction of the executive chamber~produce thrust~control the movement of throttling components ~ achieve automatic adjustment. With measurement, implementation, control of the integrated features. Available in no gas, no electricity  lace. Widely used in petroleum, chemical, power plants, light industry, printing and dyeing industry, automatic control system for a variety of equipment, gas, liquid and steam media deceleration pressure,regulator (for the valve pressure regulator) relief pressure, Pressure control) automatic control. According~the user's different conditions can choose different spool structure and different implementing agencies, in order~ achieve the best control effect. Self-operated pressure regulating valve model

Self-operated Pressure Regulating Valve model：

Pressure closed type: for the valve pressure regulator, when the valve pressure increases, the valve closed, in order~ achieve decompression, the purpose of regulating.

Pressure type: for the valve pressure regulator, when the valve pressure increases, the valve opens, in order~ achieve pressure relief, the purpose of regulating.
