Self-operated pressure regulating valve Overview
 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 place. 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.
