EATON DGM**-5 30 Design E-VLVI-SS001-E1 October 2015N-25NOperating DataPerformance DataMinimum Controlled Flow/No-Flow LeakageInternal leakage will vary from valve to valve and with thepressure differential across the check. Approximate levelsare:Pressure DropThe curves below show the pressure drop through individualflow passages. Curves labeled “metered flow/pressuredrop” refer to the pressure drop through only the passagecontaining the flow control regulating orifice. Total valveinsertion loss is a value derived from graph 1 or 2 plus theappropriate values of lines 1, 2 and 3 from graph 3.Pressure Drop Leakage*bar (psi) cc/min (in3/min)50 (725) 160 (9.5)100 (1450) 320 (19)200 (2900) 640 (38)315 (4500) 990 (60)* Equals minimum controllable flow rate at the pressures stated.Graph 1Metered flow pressure drop.Normal adjustment – “2”models (see model code,page 24).Graph 2Metered flow pressure drop.Fine adjustment – “1” models(see model code, page 24).Graph 3Free flow pressure drop acrosscheck valve.Note: “Turn” or “Turns” on curves in graphs 1 and 2, above, refer to turn ofadjustment device from fully closed position.Graph 31 – “P” port of all models exceptDGMFN-5-X-P**-30“B” and “T” ports ofDGMFN-5-X-P**-302 – “T” port of all models exceptDGMFN-5-X-P**-30“A” ports ofDGMFN-5-X-P**-303 – Pressure drop across reversefree flow check valvePressure Drop barPressure Drop psi150100100000Flow l/minFlow USgpm20 40 60 80 100 1205 10 15 20 25 3050300250200040005000350200 300010 turns8 turns6 turns1 turn1 1/2 turns2 turns4 turns150100100000Flow l/minFlow USgpm20 40 60 80 100 1205 10 15 20 25 3050300250200040005000350200 30001/2 turn2 turns3 turns4 turns8 turns7 turns1 turn644000Flow l/minFlow USgpm40 80 12010 202 20128608010012016010 140301239 turns1/2 turnPressure Drop barPressure Drop psiPressure Drop barPressure Drop psiBasic CharacteristicsMaximum flow 120 l/min (32 USgpm)Maximum operating pressure 315 bar (4500 psi)Operating temperature 20° to 50°C (70° to 120°F)Weights 3,1 kg (7 lbs)
