  EATON Vickers Screw-In Cartridge Valves V-VLOV-MC001-E4 September, 2007 F-34 PFRD/S-16 Priority flow regulator valveDescriptionThe PFR*-16 is a spooltype, screw-in, load-sens-ing priority flow regulatorcartridge valve. RATINGS AND SPECIFICATIONS Performance data is typical with fluid at 21,8 cSt (105 SUS) and 49°C (120°F)  Typical application pressure (all ports)280 bar (4000 psi)Cartridge fatigue pressure (infinite life)280 bar (4000 psi)Rated inlet flow150 L/min (40 USgpm)Temperature range-40° to 100° C (-40° to 210° F)CavityC–16–5SFluidsAll general purpose hydraulic fluids such as:MIL–H–5606, SAE 10, SAE 20, etc.FiltrationCleanliness code 18/16/13Housing materials (standard)SteelWeight cartridge only0,47 kg (1.05 lbs.)Seal kit202915-922Internal leakage164cc/min (10 in 3  /min) @ 3000 PSIDRecommended L/S orifice0.036” (not included in valve) Functional Symbols Dynamic Signal (PFRD) Profile ViewPressure Drop CurvesCartridge only 4CF2EF5LS 13 P 4CF2EF5LS 13 P 12345 LSCFPEF OperationThis valve is used in theflow control mode. Pumpflow from the valve inletport 3 is delivered first toport 4 at a fixed rate;excess flow is bypassed toport 2. The valve maintainsthe controlled flow to 4regardless of inlet pressurechange or load pressurechanges at 2 or 4. Thisvalve is typically used withopen loop load sense sys-tems in steering and brak-ing circuits. The static typeis used for less difficultapplications whereresponse or circuit stabilityis not a problem. Thedynamic type is used fordifficult applications whereresponse or circuit stabilityare critical. The load senseline connected to port 5should not exceed 2Meters (6 Feet) in length.Overpressure protection forthe circuits connected toports 2 and 4 must be pro-vided by external relief valves. The control pressureis determined by assuringadequate inlet pressure tothe steering unit and mustbe matched to the steeringunit’s required flow. Thecontrol pressure must besupplied to the valve as aminimum inlet pressure.The pressure at port 4 canvary by 10% when the loadat the excess flow port 2varies from 0 to max pres-sure.
