Proportional Directional Valve 4WRDE25V220L-6X/MXY/24A5 - Bosch Rexroth R901535494

When replacing a valve on an existing size 25 subplate, the pilot oil arrangement has to match or the axis will not move. This build expects pilot oil through X and drains it through Y, at 220 l/min nominal flow and 350 bar.

Benefits

• External X and Y arrangement, matching subplates with a separate pilot circuit.
• 220 l/min nominal flow, flow capability up to 870 l/min in size 25.
• Symbol V, three switching positions, four ports, linear characteristic.
• Internal spool position feedback for low hysteresis and repeatable positions.
• 17.5 kg weight, 350 bar operating pressure, ±10 V command value on on-board electronics.

Application

The version is used when replacing older proportional valves in presses, injection moulding machines and metallurgical plant where the existing piping stays. Before the swap, check that pilot pressure sits inside the required range. The Y drain has to run to tank without back pressure.
