4K82(D) & 4KK82(D) SERIES CHECK VALVESPILOT OPERATED - BALL TYPE4K82CYL (3)32PILOT (1)1VALVE (2)4KK82C1C2C1C27V1V2V1V2APPLICATIONPilot check valves allow flow to pass in one direction,with a low pressure drop, then prevent reverse flowuntil pilot pressure is applied. These line mountedcheck valves give control over cylinders or otheractuators, holding and locking them in position untilpilot pressure is applied.OPERATIONPressure on the valve port causes the ball to liftagainst the spring force, allowing flow to the cylinderport. Reverse flow is prevented by the check reseating.Pressure applied to the pilot port will overcome thecylinder port pressure and lift the ball from its seat,allowing return flow. In dual pilot check valves, eachpilot section is cross connected to the opposite linegiving automatic pilot operation in both directions.FEATURESThese valves use one or two 3CA80 cartridges in ahousing containing a single or double acting pilotpiston. (See page 7-131). The valve housings havethreaded ports and mounting holes for immediateinstallation into hydraulic systems. The damped pilotpiston chambers reduce damaging shocks in operation.SPECIFICATIONSFigures based on: Oil Temp = 40°C Viscosity = 40 cStRated FlowMax PressurePilot Ratio 4:1Body MaterialMounting PositionWeightSeal Kit NumberRecommendedFiltration LevelOperating TempNominal ViscosityRange80 litres/min (20 US GPM)4K82/4KK82Line mounted4K824KK824K824KK824K82-N-*W-S-3BS5540/4 Class 18/13(25 micron nominal)-20°C to +90°C5 to 500 cSt350 bar (5000 psi)Standard aluminium (up to 210 bar*)Add suffix ‘377’ for steel option.0.28 kg (0.62 lbs)0.43 kg (0.95 lbs)SK226 (Nitrile)SK226V (Viton)SK287 (Nitrile)SK287V (Viton)SK684 (Nitrile)SK684V (Viton)*For applications above 210 bar please consult our technical department or use the steel body option.Integrated Hydraulics LtdIntegrated Hydraulics IncCollins Road, Heathcote Ind.
