Modular reducing valves type HG, KG, JPG-2 and JPG-3
spool type, ISO 4401 sizes 06, 10, 16 and 25
Table D140-13/E
HG, KG, JPG are pressure reducing val-
ves, spool type , designed to operate
in oil hydraulic systems.
HG are direct, three way valves;
KG are double stage , three way
valves;
JPG are double stage , two way
valves.
Pressure adjustment is operated by loo-
sening the locking nut and turning the
setting screw in the normal model.
Optional versions with a handwheel
are available on request.
Clockwise rotation increases the pressure.
HG = ISO 4401 size 06 interface: flow
up to 50 l/min; pressure adjust-
ment up to 210 bar.
KG = ISO 4401 size 10 interface: flow
up to 100 l/min; pressure adju-
stment up to 210 bar.
JPG-2 = ISO 4401 size 16 interface: flow
up to 250 l/min; pressure adju-
stment up to 210 bar.
JPG-3 = ISO/4401 size 25 interface: flow
up to 300 l/min; pressure adju-
stment up to 210 bar.
Valves designed to operate in hydrau-
lic systems with hydraulic mineral oil or
synthetic fluid having similar lubricating
characteristics.
