Pressure Reducing Valve/Drain Separator

GD-29S-NE

*Maximum Inlet pressure 2.0MPa, applicable to high pressure equipment of high-rise building, factory, plant.
*Wetted parts are made of corrosion-resistant material (diaphragm/O ring is made of chlorinated EPDM), has excellent resistance to chlorine of tap water.
*Can be installed in any piping direction, such as horizontal or vertical.
*Closed construction could keep no external leakage even if diaphragm damaged.*Water supply law standards conformity product(E-606).
