EATON DGM**-5 30 Design E-VLVI-SS001-E1 October 2015N-5NSystemStak™ Pilot Operated ReliefValvesDGMC/DGMC2General DescriptionThese two-stage valves limit system pressure by directingflow to tank or the opposite cylinder port (A-B/B-A crossporttypes) 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 externallydrained, depending on model type. Any pressure in the line towhich these valves are drained is additive to the valve pres-sure setting.The valve pressure setting is adjustable by means of eitheran adjusting screw and locknut, a hand-knob adjuster, or amicrometer knob with keylock. External remote control/ventconnections are available on all models except crossportrelief. If required on crossport models, contact your Eatonrepresentative.Model Code12345678910111213141516Valve functionManifold or subplate mounted pressurerelief valve.Valve type2 – Dual relief cavitiesBlank – Single reliefInterface5 – ISO 4401-AC-05-4-A, CETOP RP35HANSI/NFPA D05Port operated uponA – “A” cylinder port (single, dual orcrossport types)B – “B” cylinder port (single type only)P – Pressure port (single type only)Port drained intoA – “A” cylinder portB – “B” cylinder port (crossport typeonly)T – Tank port (single or dual types)Pressure rangeA – 4 to 50 bar (60 to 725 psi)B – 4 to 100 bar (60 to 1450 psi)F – 4 to 200 bar (60 to 2900 psi)G – 4 to 315 bar (60 to 4500 psi)Adjustment deviceH – Knob adjusterK – Micrometer knob with keylockW – Screw with locknutExternal drainE – External drainOmit for internal drain models.P port acted uponB – “B” cylinder port (dual or crossporttype) Omit for single type.Port drained intoA – “A” cylinder port (crossport typeonly)T – Tank port (dual type only)Pressure rangeOmit for single type.A – 4 to 50 bar (60 to 725 psi)B – 4 to 100 bar (60 to 1450 psi)F – 4 to 200 bar (60 to 2900 psi)G – 4 to 315 bar (60 to 4500 psi)Adjustment deviceOmit for single relief models.H – Knob adjusterK – Micrometer knob with keylockW – Screw with locknutExternal drainE – External drain same as position 8Omit for single relief models.Remote control portRC – Remote control portNot available on crossport models.Gage port & thread typeGage port for P-T models only; optionalremote control (RC) and external drain(E) ports as applicable.Omit for crossport modelsB – G 1/8” (1/8” BSPF)S – SAE-4 O-ring boss port(0.4375-20 UNF-2B thread)Design number - 30 seriesSubject to change.
