1LLR SERIES DUAL RELIEF VALVEDIRECT ACTING DIFFERENTIAL AREA1LLR150POPPET TYPEP1P13P2P2APPLICATIONTo protect directional control valves or motors fromshock or surge pressures induced by changes indirection or sudden stops which create excessive loadconditions.FEATURESSoft start and stop with fast acting operation to givemaximum protection to expensive actuators. Reducesplumbing to a minimum and cartridge construction makesfor easy maintenance.OPERATIONThe dual relief is of the cross line type, where exhaustoil from one line is transferred to the other, negatingthe need for a separate tank line. It also preventscavitation when used in conjunction with a closedcentre directional valve. For greatest protection thevalve should be mounted as close to the actuator ormotor as possible.Note for single rod cylinders, anti-cavitation checkvalves and a separate tank line are necessary.
