Proportional Directional Valve 4WRKE25W6-220L-3X/6EG24ETK31/A1D3V - Bosch Rexroth R901124434

On axes that must accelerate symmetrically out of mid position, the spool symbol decides the behaviour around zero. This pilot-operated size 25 proportional valve uses symbol W6 with a linear characteristic curve, passes 220 l/min nominal flow and regulates the spool through internal position feedback up to 350 bar operating pressure.

Benefits

• Spool symbol W6, linear characteristic curve, 220 l/min nominal flow
• On-board electronics for a ±10 V command value, 24 VDC supply through a single connector
• Up to 870 l/min possible across the valve, operating pressure of 350 bar maximum
• Internal pilot oil supply and internal pilot oil return save two external lines
• FKM seals for HL hydraulic fluid, weight 17.96 kg

Technical data

Applications

The valve controls feed and pressing axes in machine tools and hydraulic presses. It sits on a manifold to ISO 4401-08-08-0-05 with four ports and three switching positions. The 7-pole (6 + PE) connector to EN 175201-804 brings supply and command signal together.
