1DDRC SERIES DUAL RELIEF VALVEWITH MAKE UP CHECKS - DIRECT ACTING1DDRC35POPPET TYPEP1P23P1TP2APPLICATIONThis 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.OPERATIONFEATURESSoft start and stop with fast acting operation to givemaximum protection to expensive actuators. Reducesplumbing to a minimum and cartridge construction makesfor easy maintenance.SPECIFICATIONSFigures based on: Oil Temp = 40°C Viscosity = 40 cStThe 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.PRESSURE DROPRated FlowMax SettingCartridge Material30 litres/min (8 US GPM)400 bar (5800 psi)Working parts hardened and groundsteel.
