4 Pilot operated pressure relief valves series R4V (DIN

24340 Form D) and R6V (DIN

24340 Form E) consist of a manually adjusted pilot stage and a seated type main stage. A vent function with a solenoid operated directional valve is available for circulation at minimum pressure. Features ? Pilot operated with manual adjustment ?

3 adjustment modes: - hand knob - acorn nut with lead seal - cylinder lock ? Remote control via port X Characteristics Function: Series R4V/R6V System pressure in port P is applied via the X gallery to the spring loaded cone in the pilot head. The pilot head controls the pressure in the Z area on top of the main cartridge which is additionally kept close by the main spring. If the pilot pressure exceeds the setting pressure the pilot cone opens and thus limits the pilot pressure. When the system pressure exceeds the pilot pressure plus the spring force, the main cartridge opens to port T and limits the pressure in port P to the adjusted level. Series R4V/R6V with vent function Additionally to the relief function, a solenoid operated vent valve connects the Z area to tank. This allows oil circulation from P toT at minimum pressure drop.The vent valve can either be a standard CETOP

03 valve (R6V) or a sandwich unit (R4V). For both types the vent position can be either at the energized or de?energized solenoid. R6V06 with vent valve R6V06 R6V06 with vent valve R4V06 with vent valve Code
