Proportional Directional Valve 4WRZE10W6-50-7X/6EG24N9TK31/A1D3M - Bosch Rexroth R900979518

The 4WRZE10W6-50-7X/6EG24N9TK31/A1D3M draws its pilot oil from an external circuit and releases it internally into the tank line. Pilot pressure therefore stays independent of load pressure without a second extra line. 50 l/min nominal flow and 315 bar operating pressure are available.

Benefits

• 50 l/min nominal flow, maximum flow 170 l/min, operating pressure up to 315 bar.
• External pilot supply through X with internal draining, only one extra line.
• Command value +/-10 V, on-board electronics, 24 VDC supply.
• Concealed auxiliary actuation for emergency and set-up movement.
• Spool symbol W6, 3 switching positions, 4 ports, ISO 4401-05-05-0-05.
• Weight 9.18 kg, NBR seals, hydraulic fluid HL, UKCA conformity.

Application

This combination proves itself in machines with an existing pilot pressure network and a short path to the tank. Positioning axes on special purpose machines and test rigs are typical. With internal draining the permitted back pressure in port T has to be observed.
