Self regulating Pressure Regulator can change differential pressure and flow before and after the valve to keep the pressure before (or after) the valve at a constant level, using the self energy of the medium to be controlled as the power source, without external power. It features flexible action, good seal property and low fluctuation of the pressure set point. Self regulating Pressure Regulator is widely used for the automatic control of the pressure-reducing stabilization and pressure-relief stabilization for the gases, liquid and steam.

Self regulating Pressure Regulator  has other advantages as smart and accurate regulating,taking up small space and simple operation and Self regulating Pressure Regulator is widely used in the pressure control of gas,steam or water in petroleum, chemical, electric power, metallurgy, food, textile, machinery, civil construction industry.
