Proportional Directional Valve 4WRKE25W8-350L-3X/6EG24TK31/F1D3M - Bosch Rexroth R901124993

Spool symbol W8 is selected when the centre position has to connect the ports differently from version E1. In the 4WRKE25W8-350L-3X this spool works at 350 l/min nominal flow and operating pressure up to 350 bar, while pilot oil arrives externally through X and drains internally.

Benefits

• Spool symbol W8, three switching positions, four ports
• 350 l/min nominal flow, flow rate up to 870 l/min
• External pilot oil supply, internal pilot oil return
• 4...20 mA current command value at the on-board electronics
• 17.8 kg weight, operating pressure up to 350 bar, NBR seals

Technical data

Applications

Valves like this sit in feed axes of machine tools and in lifting gear where the centre position has to give the actuator ports a defined behaviour. The 4...20 mA signal stays readable over long cable runs. Wiring uses the 7-pole connector (6 + PE) to EN 175201-804.
