5 Technical Information General escription Series R4V and R6V pressure relief valves feature a manual adjustment pilot stage which controls 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. 2 interfaces: Subplate, ISO 6264 (IN 2434 Form ) with VV1 vent valve (R4V) Subplate, ISO 6264 (IN 2434 Form E) with CETOP 3 vent valve (R6V) 3 pressure ranges. 3 adjustment modes: Hand knob Acorn nut with lead seal Key lock Remote control via port X. R6V6 Pressure Control Valves Series R4V and R6V (Pilot Operated) Function 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. Additionally to the relief function, a solenoid operated vent valve connects the Z area to tank. This allows oil circulation from P to T at minimum pressure drop. The vent valve can either be a standard CETOP 3 valves (mounting form E) or a sandwich unit (mounting form ). For both types the vent position can be either at the energized or de energized solenoid.

21 Technical Information General escription Series R4U subplate mounted unloading valves are used to unload a circuit at low pressure. The mechanically adjustable pressure signal to unload the main stage has to be applied to port X. The pressure differential between opening and closing is nominal 15% or 28% of the setting pressure: 15% for pressure ranges 35 Bar (575 PSI) and 28% for 15 Bar (1523 PSI) and 21 Bar (345 PSI). Typical applications are to unload the pumps in an accumulator circuit and to unload the low pressure stage of a double pump. In addition, Series R4U with vent function is vented by electrical operation. Features Pilot operated unloading valve. 3 pressure ranges. 2 switching types (series R4U with vent function). 3 adjustment modes: Hand knob Screw with locknut Key lock Pressure Unloading Valves Series R4U Performance Curves PSI 435 Bar 3 Minimum Pressure Curve Pressure p Flow (Q) % The performance curves are measured with external drain. For internal drain the tank pressure has to be added to curve. R4U.indd, dd 19

Series VM is a direct-controlled, spring loaded 3-way pressure reducing valve, that is open in neutral position. The valve closes the connection from P to A (NG6) or B to A (NG1) when the pre-set pressure is exceeded. Pressure Reducing Valves Series VM NG6 NG6 If the pressure increases due to an external influence in connection A, the spool moves and opens the connection from A to T (NG6) or A to Y (NG1) until the pre-set pressure is reached.

51 Technical Information General escription Series R5V pilot operated pressure relief valves have a similar design to the subplate mounted R4V series. The SAE flanges allow to mount the valves directly on the outlet flanges of pumps or inlet flanges of actuators to achieve a very compact design. Valves with SAE flanges can also be bolted together to combine functions without the need of a manifold block. Pressure Relief Valves Series R5V R5V 2-Port R5V 2-Port Operation The system pressure in Port A is applied to the pilot valve and to the top surface of the main poppet via an orifice in X. The hydraulically balanced main poppet is held against the seat by the main spring. In this state there is no flow through the valve. The adjusted spring force acting on the pilot cone determines the relief pressure. If the pressure in Port A exceeds the set point, the pilot cone is lifted from its seat, releasing a small pilot flow to tank. The flow through the control orifice in X creates a pressure drop which limits the pressure at the top of the main poppet to the set point. The higher system pressure in Port A now lifts the main poppet off its seat and allows flow to Port B. In the resulting float position only enough flow is passed from Port A to Port B to maintain the inlet pressure in Port A at the set point. When the pressure in Port A falls below the set point, the hydraulic balance on the main poppet is restored. The main spring then forces the main poppet to close.

70 Technical Information General escription Series R4V pilot operated, pressure relief valves for in-line mounting have a similar design to the subplate mounted R4V series. For single functions where no manifold blocks are used, the valves can be directly placed in the pipework. The R4V valves are available with 2 ports (L-body) for in-line relief function or with 3 ports (T-body) for relief functions in the bypass. Pressure Relief Valves Series R4V Operation The system pressure in Port A is applied to the pilot valve and to the top surface of the main poppet via an orifice in X. The hydraulically balanced main poppet is held against the seat by the main spring. In this state there is no flow through the valve. The adjusted spring force acting on the pilot cone determines the relief pressure. If the pressure in Port A exceeds the set point, the pilot cone is lifted from its seat, releasing a small pilot flow to tank. The flow through the control orifice in X creates a pressure drop which limits the pressure at the top of the main poppet to the set point. The higher system pressure in Port A now lifts the main poppet off its seat and allows flow to Port B. In the resulting float position only enough flow is passed from Port A to Port B to maintain the inlet pressure in Port A at the set point. When the pressure in Port A falls below the set point, the hydraulic balance on the main poppet is restored. The main spring then forces the main poppet to close. Features Pilot operated with manual adjustment. 2 interfaces: L-body (R4V6-SAE 12, R4V1-SAE 2) T-body (R4V3-SAE 8, R4V6-SAE 16) 3 pressure stages. 3 adjustment modes: Hand knob Acorn nut with lead seal Key lock With optional vent function.
