Proportional Directional Valve 4WRZE25E220-7X/6EG24N9K31/A1M - Bosch Rexroth R901184538

For many axes the simplest version is the right one. The 4WRZE25E220-7X/6EG24N9K31/A1M needs neither an external pilot oil supply nor a separate drain and still meters 220 l/min nominal flow at 350 bar operating pressure.

Benefits

• Internal pilot oil routing, so the valve gets by with ports P, A, B and T.
• 220 l/min nominal flow and up to 870 l/min maximum flow.
• A ±10 V command value, fed straight from an existing analogue card.
• Spool symbol E, ISO 4401-08-08-0-05 mounting pattern, 20.24 kg valve mass.
• 350 bar operating pressure, NBR seals, HL hydraulic fluid, 24 VDC supply.

Application

Suited to standard axes on presses, test rigs and forming machines with a stable pump supply. Internal pilot oil routing keeps the installation effort low. For plants with strongly varying pressure the same series offers versions with external pilot oil.
