Product Description

DP27/DP27G/DP27R/DP27Y PILOT DIAPHRAGM TYPE STEAM/WATER/GAS PRESSURE REDUCING VALVE/PRESSURE REGULATOR/PRESSURE RELIEF VALVE/DECOMPRESSION VALVE

Product Description

DP27/DP27G/DP27R/DP27Y Pilot Operated Pressure Reducing Valve  is the new type pilot diaphragm pressure reducing valve developed by our company. It is greatly improved on basis of normal pressure reducing valve. The membrane use new material, enlarging the working area, so the slight change of upper pressure or lower pressure can be fed back to membrane of main valve, and adjust the opening of main valve to ensure the constant pressure of lower stream pressure.
Note: A variable rate conical pressure adjustment spring is fitted providing a down stream pressure range of 0.2-17bar g.
