Proportional Directional Valve 4WRKE25W6-220L-3X/6EG24K31/A1D3V - Bosch Rexroth R901108789

Systems with a separate, pressure-controlled pilot circuit call for a valve whose pilot oil arrives from outside and is returned outside. This size 25 proportional valve is built that way, processes the ±10 V command value with on-board electronics and sets the spool to symbol W6 at 220 l/min nominal flow.

Benefits

• External pilot oil supply and external pilot oil return for systems with a separate pilot circuit
• 220 l/min nominal flow, up to 870 l/min permitted across the valve
• ±10 V command value, 24 VDC supply, on-board electronics at the valve
• Spool symbol W6 with a linear characteristic curve, three switching positions, four ports
• FKM seals, operating pressure up to 350 bar, weight 17.78 kg
