Proportional Directional Valve 4WRZE25E220-7X/6EG24K31/A1M - Bosch Rexroth R900954671

A drive rated at 220 l/min nominal flow needs a stage that sets direction and flow at the same time. The 4WRZE25E220-7X with spool symbol E covers up to 870 l/min peak flow, works up to 350 bar operating pressure and does without a built-in pressure reducing stage.

Benefits

• 220 l/min nominal flow at 350 bar drives large cylinders without an extra stage
• Peak flow up to 870 l/min leaves headroom for fast traverse movements
• On-board electronics handle the plus/minus 10 V command value without a separate amplifier card
• Subplate mounting to ISO 4401-08-08-0-05 keeps the size 25 hole pattern
• External pilot oil supply and external pilot oil return separate the pilot stage from the main circuit
• NBR seals and 24 V DC through a connector, 7-pole (6 + PE) according to EN 175201-804

Applications

Typical duty covers presses, injection moulding machines and test rigs where a large cylinder is positioned independently of load. The external pilot oil supply suits circuits whose main pressure varies widely. Hydraulic fluid HL and NBR seals match standard mineral oil operation.
