Proportional Directional Valve 4WRTE32W8-400L-4X/6EG24EK31/A1M - Bosch Rexroth R901295949

Back pressure in the tank line shifts the null point of an internally drained pilot stage. The 4WRTE32W8-400L-4X avoids that with an internal supply and an external pilot oil return, at 400 l/min nominal flow and 350 bar.

Benefits

• Internal pilot oil supply with external return, insensitive to back pressure in the return line.
• 400 l/min nominal flow with up to 1600 l/min maximum flow.
• Symbol W8 with a linear characteristic and internal piston position feedback.
• ±10 V command value, on-board electronics on 24 V DC.
• 37.6 kg weight, 350 bar operating pressure, NBR seals, connection diagram ISO 4401-10-09-0-05.

Technical data

Applications

Intended for systems with return filters, coolers or long tank lines that build noticeable pressure on the return side. Separate draining keeps the pilot circuit clear of it and the null position stable.
