Pressure Reducing Valve
|
GD-29S-NE
Inlet pressure 2.0 MPa , Wetted parts SCS , Chlorine resistant *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). |
