Proportional Directional Valve 4WRDE16V220L-6X/MXT/24A5 - Bosch Rexroth R901509813

When working pressure falls below the minimum pilot pressure a pilot operated valve becomes sluggish. The 4WRDE16V220L-6X/MXT/24A5 therefore draws its pilot oil from a separate circuit through port X while the return stays internal. At 220 l/min nominal flow and symbol V the characteristic curve remains linear across the whole control range.

Benefits

• External pilot oil feed secures pilot control at low or fluctuating working pressure.
• Internal pilot oil return, so only one additional line is needed instead of two.
• 220 l/min nominal flow and a maximum of 460 l/min at 350 bar.
• Spool symbol V with a linear characteristic curve and three switching positions.
• Valve weight 10 kg with an analogue ±10 V command value.

Application

A typical use is in systems with a wide pressure range, for example test rigs and control axes on forming machines. The NBR seals suit mineral oil HL. The subplate pattern is ISO 4401-07-07-0-05 and the plug follows EN 175201-804.
