Pressure Reducing valve (Adjustable type)

Description of Pressure Reducing valve (Adjustable type) This valve is mainly used in pipeline system in the fields of high-rises, mines, factories, pharmaceuticals and foodstuff, tec., functions to lower high pressure at upper stream to normal service pressure of lower stream. 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 thescrew of pilot valve.
