Proportional Directional Valve 4WRZE10W6-25-7X/6EG24N9EK31/A1D3M - Bosch Rexroth R901079515

The 4WRZE10W6-25-7X/6EG24N9EK31/A1D3M takes its pilot oil internally from the pressure port and drains it externally. The pilot stage therefore stays independent of return pressure without calling for a dedicated pilot source. The +/-10 V command value drives the spool of symbol W6 at 25 l/min nominal flow.

Benefits

• 25 l/min nominal flow, maximum flow 170 l/min, operating pressure up to 315 bar.
• Internal supply from P and external draining through Y, only one extra line.
• Command value +/-10 V, on-board electronics with internal position feedback, 24 VDC.
• Concealed auxiliary actuation for the de-energised case.
• Spool symbol W6, 3 switching positions, 4 ports, ISO 4401-05-05-0-05.
• Weight 9.02 kg, NBR seals, UKCA conformity.

Technical data

Application

This combination suits plants without a separate pilot pressure network whose return line is nevertheless loaded by several consumers. External draining keeps control behaviour steady. Pressure has to be present in port P throughout the movement.
