Proportional Directional Valve 4WRZE25E220-7X/6EG24N9ETK31/F1D3M - Bosch Rexroth R901034829

Every extra control line on a manifold is one more place to mix up or forget during assembly. This version needs none, because pilot supply and drain run internally and the reducing stage sits inside the valve as well.

Benefits

• No X and no Y line, which removes two possible assembly mistakes.
• A pressure reducing valve in the pilot line caps the internally tapped pilot pressure.
• Flow rating 220 l/min, maximum flow 870 l/min, operating pressure up to 350 bar.
• Spool symbol E, three switching positions, four ports.
• Current command 4...20 mA, on-board electronics on 24 VDC, mass 20.76 kg.

Applications

Valves like this belong on machines built in series and commissioned within a short time, such as injection moulding machines and special machinery in series production. The fitter connects four lines and one cable, nothing else. The UKCA entry to SI2016/1091 documents electromagnetic compatibility.
