Pressure Reducing Valve


* 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).
