Proportional Directional Valve 4WRZE10E25-7X/6EG24N9TK31/A1D3M - Bosch Rexroth R901155530

The 4WRZE10E25-7X/6EG24N9TK31/A1D3M draws its pilot oil from an external circuit and releases it internally into the tank line. At 25 l/min nominal flow the spool of symbol E follows the +/-10 V voltage command value, and operating pressure reaches 315 bar. A concealed auxiliary actuation is built in.

Benefits

• 25 l/min nominal flow, maximum flow 170 l/min, operating pressure up to 315 bar.
• External pilot supply through X, internal draining, the Y line is dropped.
• Command value +/-10 V, on-board electronics, 24 VDC supply.
• Concealed auxiliary actuation for emergency and set-up movement.
• Spool symbol E, 3 switching positions, mounting pattern ISO 4401-05-05-0-05, size 10.
• Weight 8.46 kg, NBR seals, hydraulic fluid HL, UKCA conformity.

Application

This variant is asked for in plants with an existing pilot pressure source and a short path to the tank, such as test rigs and adjusting units. Pilot pressure stays independent of working pressure. With internal draining, back pressure in port T has to be limited.
