Pressure Reducing and Maintaining Valve Products

YB410, YB416, YB425 pressure reducing and maintaining valve, is a kind of piston pressure control valve. Diameter is less than DN50, the proposal chooses (Y110 and Y116 (threaded connections) diaphragm-type pressure-reducing valve, Diameter is not less than DN50, the proposal chooses (Y410 and Y416 (flange-connection) piston valve. These valves are adjustable pressure-reducing valve, the pressure can be adjusted to the requirement before use, back-pressure always reduce to and maintain the setting value after using, can not change with the front-pressure and flow fluctuation. Select high quality material(diaphragm is nylon enhanced rubber diaphragm), with reliable performance and long service life.
