Proportional Directional Valve 4WRZE25W6-220-7X/6EG24N9ETK31/A1D3V - Bosch Rexroth R900951208

When the design calls for spool symbol W6 and the manifold offers no pilot ports, this is the variant that remains. It delivers 220 l/min nominal flow, routes pilot oil internally and follows a ±10 V command value.

Benefits

• Spool symbol W6 combined with a fully internal pilot circuit
• 220 l/min nominal flow against a valve maximum of 870 l/min
• Operating pressure up to 350 bar, four ports to ISO 4401-08-08-0-05
• Command value ±10 V, supply 24 VDC through a 7-pole connector (6 + PE)
• Mass 20.62 kg, FKM seals released for HL hydraulic fluid

Application

The valve is used on medium-power axes whose manifold is already machined and will get no additional pilot passages. The command value normally comes from an axis controller with an analogue output. The tank line has to stay almost pressureless even at full motion.
