Proportional Directional Valve 4WRTE27V500P-4X/6EG24EK31/A1M - Bosch Rexroth R901212549

A return filter or a cooler builds back pressure that disturbs pilot control. This version of the 4WRTE27V500P still draws pilot oil internally but discharges it through a dedicated line, and controls 500 l/min from a plus/minus 10 V voltage command.

Benefits

• Internal supply, external pilot return, insensitive to back pressure in the return line.
• Command value plus/minus 10 V, direct connection to analogue outputs without a converter.
• 500 l/min nominal flow, up to 1000 l/min in size 27.
• Fine control range, spool symbol V, with internal piston position feedback.
• 270 bar operating pressure, NBR seals, hydraulic fluid HL.
• 19.5 kg weight, connection diagram ISO 4401-08-07-0-05.

Applications

The variant belongs in systems with a return filter, a cooler or a long tank line, for example presses and test centres. The Y line runs to tank without a restrictor. Installation otherwise matches the internally returned version of the same series.
