1LLRC SERIES DUAL RELIEF VALVEWITH MAKE UP CHECKS - DIRECT ACTING1LLRC75POPPET TYPEP1P23P1TP2THROUGH PRESSURE PORTSP1TP2APPLICATIONThis is a dual relief with make up checks. Ideal for useto protect a system where relief volumes are differentsuch as in a single rod cylinder or where leakage maycause cavitation as in the case of motors with a casedrain. It can also be used to protect directional valveswhen they have a closed centre condition.OPERATIONThe valve functions as a cross line relief passing oilfrom one line to the other but with an extra tank portwhich allows make up flow or extra exhaust flow totake place.FEATURESSoft start and stop with fast acting operation to givemaximum protection to expensive actuators. Reducesplumbing to a minimum and cartridge relief valves makefor easy maintenance.SPECIFICATIONSFigures based on: Oil Temp = 40°C Viscosity = 40 cStRated FlowMax Setting150 litres/min (40 US GPM)350 bar (5000 psi)PRESSURE DROPCartridge MaterialWorking parts hardened and groundsteel.
