Proportional Directional Valve 4WRTE32V1-600L-4X/6EG24ETK31/A1M - Bosch Rexroth R901022150

Where a manifold carries no dedicated pilot lines, the internal pilot oil supply plus internal return of the 4WRTE32V1-600L-4X/6EG24ETK31/A1M saves two drillings along with two fittings. The main spool with symbol V1 releases 600 l/min nominal flow, driven by a +/-10 V signal at 350 bar operating pressure.

Benefits

• Internal pilot oil supply with internal pilot oil return, no external pilot lines required.
• Spool symbol V1, 3 switching positions, 4 ports, 600 l/min nominal flow.
• Voltage command value +/-10 V, directly compatible with the analogue outputs of common axis controllers.
• Up to 1600 l/min maximum flow at 350 bar operating pressure in size 32.
• On-board electronics, 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• NBR seals for hydraulic fluid HL, mounting pattern ISO 4401-10-09-0-05, mass 37.1 kg.

Applications

Internal pilot supply matches manifolds built without a separate pilot pressure circuit, such as compact press power units plus test benches. It requires sufficient pressure in port P throughout the whole movement. Spool position feedback keeps the opening degree repeatable from cycle to cycle.
