Proportional Directional Valve 4WRZE25E220-7X/6EG24N9ETK31/F1M - Bosch Rexroth R900704949

At the end of a long pipe run a valve should ask for as few ports of its own as possible. This 4WRZE25 with spool symbol E manages with P, T, A and B because pilot supply and return run internally, while delivering 220 l/min nominal flow at 350 bar.

Benefits

• Internal pilot supply and internal return, no additional ports on the manifold.
• 220 l/min nominal flow, maximum flow 870 l/min.
• 4...20 mA current command keeps the signal stable over long cable runs.
• On-board electronics at the valve, 24 VDC supply through a 7-pole connector (6 + PE).
• 350 bar operating pressure with three switching positions and four ports.

Applications

The version is intended for feed axes and clamping movements in machines with constant network pressure. Because pilot oil is taken internally, system pressure must stay above the minimum pilot pressure at all times. HL hydraulic fluid is used, sealed with NBR.
