This Diaphragm Type Adjustable Pressure Reducing Sustaining Valve is mainly used in pipeline system in the field of high-rises,mines,factories,pharmaceuticals and foodstuff etc. , functioned to reduce pressure.
To control the fixed outlet pressure of valve not to be affected by the variations of inlet pressure and flow rate for effective decompression, the precise and steady outlet pressure can be obtained by only adjusting the bolts of pilot valve
