EATON DGM**-5 30 Design E-VLVI-SS001-E1 October 2015N-21NOperating DataPerformance DataDGMR Performance CurvesInsertion LossesThese curves show the typical pressure drop for each flowpath in the valve for fluid viscosity range 21-32 cSt(100-150 SSU).The total insertion loss for the valve is calculated by summingthe losses through each of the four flow paths.1. “P” port for all models.“A” port of DGMR-5-B*-30“B” port of DGMR-5-A*-302. “T” port for all models.3. Free flow through service port of counterbalance.4.
