Pressure Reducing Valve
|
GP-1000HEN
* GP-1000HEN can be replaced easily from existing valve because it complies with face-to-face dimensions of the EN standard. * Respond very sharply to the fluctuation of inlet pressure and the change of the flow rate, so that the reduced pressure can be kept at a constant level. * Pressure adjustment is easy, and the set pressure range is wide. * Compliant with the standard of SHASE-S106 Pressure Reducing Valves (by the Society of Heating, Air-Conditioning and Sanitary Engineers of Japan). |
