Proportional Directional Valve 4WRZE25E220-7X/6EG24N9EK31/F1V - Bosch Rexroth R901122588

The valve meters direction as well as volume to spool symbol E at 220 l/min nominal flow, and at 350 bar the flow limit is 870 l/min. The command value is fed as a 4...20 mA current, which secures signal transmission over longer distances.

Benefits

• 220 l/min nominal flow at 350 bar, flow limit 870 l/min
• Current command 4...20 mA, sturdy against interference on long cable runs
• Internal pilot oil supply, external pilot drain against back pressure in the return
• Spool symbol E, 3 switching positions, concealed manual override
• FKM seals for HL fluid, UKCA to SI2016/1091, mass of 20.58 kg

Applications

The build fits forming presses, test benches as well as lifting gear of medium volume demand. An external pilot drain stops return pressure from upsetting the pilot stage. On-board electronics make an amplifier card in the cabinet unnecessary.
