Inlet / Outlet Pressure Reduction Automatic Control Valve High Regulating Precision Level
Self-operated pressure double seats control valve
General
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 degrees steam condition.
Characteristics
1, Without any external driving energy, low cost, Suitable for explosive environment
2, Simple structure, little maintenance work;
3, The set point can be adjusted and the range is wide, convenient for the user to do continuous adjustment;
4, Body pressure, convenient pipe installation
5. Using the pressure balance valve structure, no packing, frictionless movable components, sensitive control, high control precision.
