Proportional Directional Valve 4WRZE25W6-220-7X/6EG24N9EK31/A1V - Bosch Rexroth R900959830

An internal transducer reports spool position, so the motion tracks the plus to minus 10 V command profile closely. The valve releases 220 l/min nominal flow at 350 bar operating pressure, with a flow limit of 870 l/min.

Benefits

• Position-controlled main spool with internal feedback for repeatable profiles
• 220 l/min nominal flow, 870 l/min flow limit at 350 bar
• Analog voltage command plus to minus 10 V, 24 VDC supply
• Internal pilot oil supply, external pilot drain, spool symbol W6
• FKM seals for HL fluid, UKCA to SI2016/1091, mass 20.4 kg

Applications

Injection moulding machines, die casting plants as well as indexing presses call for exactly this mix of volume plus control quality. The electronics sit on the valve, an amplifier in the cabinet becomes unnecessary. A concealed manual override moves the axis during commissioning without power.
