DIRECT -ACTIVATED PRESSURE REDUCING VALVE ( Duplex Stainless Steel )-1

DIRECT -ACTIVATED PRESSURE REDUCING VALVE ( Duplex Stainless Steel ) Excellent corrosion resistance and increased strength, duplex stainless steels are popular in a variety of industries such as Offshore and near-shore operations, oil drilling, desalination, water treatment, chemical, and other industrial operations. The gate is balanced-pressure designed, which will not influence the outlet pressure caused by unstable inlet pressure. Pressure needed from fully-closed gate to fully-opened gate : 1.5 kgf/cm2. When the outlet pressure responds directly to the pressure control chamber and adjusts the setting pressure, it responds quickly and adjusts the pressure accurately. Unique piston-diaphragm design outperform traditional type by better ability of sustaining pressure and less leakage. Pressure Adjusting Range : 1~6 kgf/cm2 ( 1 kgf/cm2 = 14.2 psi) 4~10 kgf/cm2 8~13 kgf/cm2 Applied Temperature : -15~85 °C Valve Body Testing Pressure : 35 kgf/cm2 Maximum Applied Pressure : 25 kgf/cm2 ◎ Special order can be arranged for higher pressure adjustment range.
