Proportional Directional Valve 4WRZE25E220-7X/6EG24K31/F1M - Bosch Rexroth R901468204

A current signal of 4 to 20 mA makes a broken cable visible at once, because the zero point lies outside the valid range. This pilot-operated proportional directional valve of the 4WRZE series works that way and meters 220 l/min nominal flow at 350 bar.

Benefits

• 4 to 20 mA command value, a cable break is detected as a fault by the controller.
• 220 l/min nominal flow at 350 bar, flow up to 870 l/min in size 25.
• External pilot oil supply and external return for a dedicated pilot circuit.
• Spool symbol E, 3 switching positions, on-board electronics with internal spool position feedback.
• 20.51 kg installed weight, UKCA declaration for electromagnetic compatibility.

Applications

Used on axes whose failure has to be detected, such as lifting gear, lock gates and test rigs carrying a load. Diagnosis of the command value range is handled by the machine controller. Connection diagram ISO 4401-08-08-0-05.
