Proportional Directional Valve 4WRZE25E220-7X/6EG24N9EK31/F1D3V - Bosch Rexroth R978911947

Internal pilot oil pick-off at high system pressure only works if the pilot stage is protected. This pilot-operated proportional directional valve in size 25 has the pressure reducing valve built in, metering 220 l/min nominal flow at 350 bar operating pressure.

Advantages

• Built-in pressure reducing valve holds pilot pressure independent of system pressure up to 350 bar.
• 220 l/min nominal flow, with 870 l/min permitted as maximum.
• Internal pilot oil supply with external return leaves only the Y port to pipe.
• 4 to 20 mA command value on the on-board electronics, immune to noise over long cables.
• Concealed auxiliary actuation, FKM seals, 20.58 kg, UKCA evidence.

Applications

Intended for high-pressure circuits lacking a pilot supply of their own, on presses, clamping systems, test rigs. Integrating the pressure reducing valve saves a separate component in the manifold along with one more potential leak point.
