EATON DGM**-3 40/41 Design E-VLST-BB001-E April 2015M-17MSystemStak™Flow Restrictor ValvesDGMFN-3-41General DescriptionThese valves regulate flow by means of an adjustable orificewhich is not pressure compensated, and flow throughthe valve is entirely dependent upon pressure drop at anyparticular setting of the orifice.Dual service-line models with an integral non-return valvearound each control orifice provide for meter-in or meter-outcontrol; single line versions of these are available.For flow restriction in P or T lines (where reverse free flow isnot required) models without check valves are available.Adjustment options are either screw/locknut or handknob.Typical SectionModel CodeDGMFN -3- * -* * * (-* * *) - 411 2 3 4 5 6 7 8Direction of flow control (withrespect to machine actuator)X – Meter-in control, applicable to linesA and BY – Meter-out control, applicable tolines A and BZ – Meter-in control, line P only andmeter-out control, line T only.Location of control function(single model or first line ofdual model)P – Line P (single model only)T – Line T (single model only)A – Line A (single model or first line ofdual model)B – Line B (single model only)Type of control needle/orifice(single model or first line of dualmodel)1 – Fine control2 – Standard controlAdjuster type (single model orfirst line of dual model)H – HandknobW – Screw/locknutControl in second lineB – Line B (use for dual models with“A” specified at )Omit for single modelsType of control needle/orifice(second line of dual models)Options as inOmit for single modelsAdjuster type (second line of dualmodels)Options as inOmit for single modelsDesign number, 41 seriesSubject to change.
