Serie PRESSURE REDUCING VALVE.

 

ZZY Series of Self-operated Control Valve,there is no need for any external power source,only used fluid own energy to adjusted the valve opening automatically, and pressure set value can be adjusted freely during on working condition. With advantages of quick-opening flow characteristic, flexible operation,good sealing performance,stable fluid pressure,high regulating precision level and low leakage etc.It is widely used in automatic control of the inlet-valve and outlet-valve pressure reduction, stabilization of the fluids, such as air, liquid and vapor in various industrial equipments,like industries in petroleum, chemical engineering,electric power,metallurgy,food, light textile,machinery manufacturing and residential buildings etc. With the condenser, it can continuous on working under 350℃steam condition.
