Proportional Directional Valve 4WRZE25W8-220-7X/6EG24ETK31/F1D3M - Bosch Rexroth R900973865

The fewer lines running to a valve manifold, the fewer places it can leak. The 4WRZE25W8-220-7X/6EG24ETK31/F1D3M therefore uses internal pilot oil supply and internal return while still metering 220 l/min nominal flow at 350 bar.

Benefits

• Internal pilot oil supply and internal pilot oil return save two fittings per valve.
• The integrated pressure reducing valve keeps pilot pressure inside limits at system pressure up to 350 bar.
• 220 l/min nominal flow, 870 l/min maximum flow, spool symbol W8.
• A 4 ... 20 mA current command with broken wire detection below 4 mA.
• UKCA conformity including electromagnetic compatibility to SI2016/1091.

Applications

Suited to compact valve manifolds in series machinery where assembly time and leak points matter. Operating pressure of 350 bar reaches the valve without any dedicated pilot feed. HL hydraulic fluid, NBR seals.
