Proportional Directional Valve 4WRDE10V100L-6X/VXT/24A1 - Bosch Rexroth R901562135

In circuits with strongly varying system pressure the pilot stage has to stay independent. The 4WRDE10V100L-6X/VXT/24A1 is fed with pilot oil from outside, returns it internally into the tank channel and, with electrical spool position feedback, meters 100 l/min nominal flow in size 10.

Benefits

• External pilot oil supply keeps the pilot stage working when system pressure drops away
• Internal pilot oil return, so the drain needs no separate Y line
• 100 l/min nominal flow, max. flow 170 l/min, maximum operating pressure 350 bar
• Electrical spool position feedback with a linear characteristic, spool symbol V
• ±10 V command on on-board electronics, 24 VDC supply, 7-pole connector (6 + PE)
• FKM seals for HL hydraulic fluid, weight 7.5 kg, interface ISO 4401-05-05-0-05

Applications

The valve suits axes whose system pressure falls far during rapid traverse or decompression, for example accumulator circuits and presses with a prefill and a main cylinder. The external supply is taken from a dedicated pilot pressure source while the drain stays inside the valve. The FKM seals are released for HL hydraulic fluid and mounting follows ISO 4401-05-05-0-05.
