Proportional Directional Valve 4WRZ25E1-220-7X/6EG24N9K4/M - Bosch Rexroth R900244673

A dedicated, temperature-controlled pilot circuit keeps pilot control working after a cold start the same way it does later in operation. The 4WRZ25E1-220-7X/6EG24N9K4/M can be tied to such a circuit through external supply and external return and controls 220 l/min nominal flow.

Benefits

• External supply and external return, temperature and pressure of the pilot oil can be managed apart from the working circuit.
• 220 l/min nominal flow, flow up to 870 l/min, spool symbol E1 in size 25.
• 20.1 kg weight, 350 bar maximum operating pressure, four ports, three switching positions.
• Concealed auxiliary actuation, protected against accidental operation.
• NBR seals, HL hydraulic fluid, 24 VDC through a 7-pole (6 + PE) plug to EN 175201-804.

Applications

The valve serves machines that must deliver dimensional accuracy shortly after switch-on, for example testing machines and forming plants. The conditioned pilot circuit is connected through X and Y. The working circuit stays independent of it.
