Proportional Directional Valve 4WRTE32W6-400P-4X/6EG24ETK31/F1V - Bosch Rexroth R901216121

The 4WRTE32W6-400P-4X/6EG24ETK31/F1V relies on the W6 spool with fine control range while limiting nominal flow to 400 l/min. Together that yields a wide fine range around centre. A 4 to 20 mA current command plus internal pilot routing keep the wiring effort small.

Benefits

• Spool symbol W6 with fine control range, 400 l/min nominal flow for accurate approach.
• Reserve up to 1600 l/min maximum flow, operating pressure to 350 bar, size 32 body.
• Current command value 4 to 20 mA, robust against interference on long cable runs.
• Internal pilot oil supply with internal pilot oil return, no extra lines in the manifold.
• FKM seals for hydraulic fluid HL, mass 37.22 kg.
• On-board electronics, 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.

Applications

The valve suits infeed axes plus closing axes whose last millimetres must be travelled slowly with repeatable accuracy, for example on plastics machinery or forming presses. Subplate mounting follows ISO 4401-10-09-0-05, offering 3 switching positions across 4 ports.
