Direct Activated Pressure Reducing Valve

Size Range : 1/2″ to 3″ Screwed / Flanged Silent Features The gate is designed for opening status, which will not fluence the water supply function under unstable inlet pressure condition. When the outlet pressure responds directly to the pressure control chamber and the setting pressure, it responds quickly and adjusts the pressure accurately. Pressure Adjusting Range : 1 ~ 5 kgf/cm2, 4 ~ 9 kgf/cm2, (special order is needed for other range) Valve Body Testing Pressure : 24 kgf/cm2 Maximum Applied Pressure : 16 kgf/cm2 Pressure needed form fully-closed gate to fully-opened gate 1 kgf/cm2 (1 kgf/cm2 = 14.2 psi) Applied Temperature : -15 ~ 80 °C Applied Condition : Fluid & Air Dimensions : (All Dimensions are in mm) Valve Model Valve Size L H CV Weight Approx.
