 Pilot Operated Relief 

Valves

DGMC/DGMC2 
General Description

These two-stage valves limit system pressure by directing 

flow to tank or the opposite cylinder port (A-B/B-A crossport 

types) when system pressure reaches the valve setting.
Pressure control may be obtained in “A”, “B”, “A” and “B”, 

or “P” port, and pilot flow may be internally or externally 

drained, depending on model type. Any pressure in the line to 

which these valves are drained is additive to the valve pres-

sure setting.

 

 

The valve pressure setting is adjustable by means of either 

an adjusting screw and locknut, a hand-knob adjuster, or a 

micrometer knob with keylock. External remote control/vent 

connections are available on all models except crossport 

relief. If required on crossport models, contact your Eaton 

representative.
