1LR SERIES RELIEF VALVEDIRECT ACTING DIFFERENTIAL AREA1LR300POPPET TYPE22PRESSURE (2)TANK (1)1APPLICATIONIdeal for intermittent duty as protection againstoverload or surge conditions for all types of actuators.Very fast acting and extremely dirt tolerant.FEATURESDirt tolerant, robust and consistent with good pressure riseto increase in flow characteristics for a direct acting valve.Cartridge construction provides for maximum flexiblity inmounting at the point where it is most needed.OPERATIONPressure acts over the differentail area between theseat and seal on the poppet. When the pressureexceeds the setting, the valve opens, allowing reliefflow to tank, washing contaminant away from the seat.SPECIFICATIONSFigures based on: Oil Temp = 40°C Viscosity = 40 cStRated FlowMax SettingCartridge Material380 litres/min (100 US GPM)350 bar (5000 psi)Working parts hardened and groundsteel.
