1CE SERIES OVERCENTRE VALVEPILOT ASSISTED RELIEF WITH CHECK1CE120VALVE (2)PILOT (3)1CYL (1)326APPLICATIONOvercentre valves give static and dynamic control ofloads by regulating the flow into and out of hydraulicactuators. When installed close to or within anactuator, the overcentre valve will stop runaway in theevent of hose burst and if open centre directionalcontrol valves are used, will allow thermal expansionrelief of the hydraulic fluid.The overcentre cartridge is ideal for mounting directlyinto a cavity machined in the body of the cylinder, motoror rotary actuator. The cartridge can also be mounteddirectly to the ports via a specifically machined body aspart of a Hydraulic Integrated Circuit or single unit, orcontained within one of our standard line bodies.Single overcentre valves are normally used when theload is unidirectional, for example an aerial platform orcrane and dual overcentre valves are used forcontrolling loads in both directions for motorapplications or for cylinders going over centre.OPERATIONThe check section allows free flow into the actuatorthen holds and locks the load against movement. Thepilot assisted relief valve section will give controlledmovement when pilot pressure is applied. The reliefsection is normally set to open at a pressure at least1.3 times the maximum load induced pressure but thepressure required to open the valve and allow movementdepends on the pilot ratio of the valve. Foroptimisation of load control and energy usage, achoice of pilot ratios is available.The pressure required to open the valve and startactuator movement can be calculated as follows:Pilot Pressure = (Relief Setting) - (Load Pressure)Pilot RatioFEATURESAllows quick, easy field service - reduces down time.Smooth, sure performance.PILOT RATIOS3.5:1 (Standard) Best suited for applications where loadvaries and machine structure caninduce instability.8:1 Best suited for applications where loadremains relatively constant.SPECIFICATIONSFigures based on: Oil Temp = 40°C Viscosity = 40 cStRated FlowMax SettingCartridge MaterialBody MaterialMounting PositionCavity NumberTorque Cartridgeinto CavityWeightSeal Kit NumberRecommendedFiltration LevelOperating TempLeakageNominal ViscosityRange120 litres/min (32 US GPM)Max Load InducedPressure: 270 bar (4000 psi)Relief Setting 350 bar (5000 psi)Working parts hardened and groundsteel.
