Proportional Directional Valve 4WRZ25E325-7X/6EG24ETK4/D3M - Bosch Rexroth R900732622

Anyone moving a large axis continuously while keeping the pipework small will find both in the 4WRZ25E325-7X/6EG24ETK4/D3M: 325 l/min nominal flow in size 25 and a pilot stage that takes control oil internally and gives it back internally.

Benefits

• 325 l/min nominal flow, up to 870 l/min peak flow at 350 bar maximum operating pressure.
• Pilot oil supplied and drained internally, neither a pilot line nor a drain line has to be routed.
• Spool symbol E, three switching positions, four ports on the ISO 4401-08-08-0-05 pattern.
• 20.4 kg weight, NBR seals for HL hydraulic fluid on a mineral oil base.
• 24 VDC through a 7-pole (6 + PE) plug to EN 175201-804, command value handled by external electronics.

Applications

It is used on forming presses and lifting axes whose control circuit is not built up separately. Because the pilot stage draws from the main channel, sufficient pilot pressure must be present there during operation. For circuits with long return paths the version with an external pilot drain is the suitable alternative.
