The gate adopts NO design, hence water supply will not be affected due to instability in inlet pressure. The internal pressure control chamber adopts diaphragm design, hence the function and life-time will not be affected by water mpurity. Besides, there isl no leakage by this design. When the outlet pressure directly responds to pressure control chamber to adjust setting pressure the response is sensitive and adjustment can be very precise. ¡¡ Size Type H L 2" Flange 150 190 2" Thread 150 190 2.5" Flange 165 210 3" Flange 200 225 4" Flange 220 250       Adjusting range¡G    0.2kgf/cm2 ¡ã4kgf/cm2    3kgf/cm2 ¡ã7kgf/cm2 Test pressure for valve body 21kgf/cm2   Pressure adjusting error +/-0.1kgf/cm2   Applied temperature:   -15C to 80C ¢J   The pressure gauge indicates the pressure in outlet.
