1. The GP-1000ENcan be replacedeasilyfrom existingvalve becauseit complieswith face-to-face dimensionsof the EN standard.

2. Thesevalvesrespondvery sharplyto the fluctuationof inletpressureand the changeof the flow rate, so that the reducedpressurecan be keptat a constantlevel.

3. Pressureadjustmentis easy,and the set pressurerangeis wide.

4. Thesevalvescomplywith the standardof SHASE-S106PressureReducingValves(The Societyof Heating,Air-Conditioning and SanitaryEngineersof Japan).
