ZZYP Self Operated Pressure Regulating Valve product details

ZZYP Self Operated Pressure Regulating Valve Overview
ZZYP Self Operated Pressure Regulating Valve produced and sold by Baigang valve group 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.
