First, the self-pressure regulator valve Overview
 ZZYP-type self-pressure regulator valve is a need without additional energy, the use of the controlled media its own energy as a power source, the introduction of the executive chamber~produce thrust~control the throttle element movement~automatically adjust. 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.
