Proportional Directional Valve 4WRZ10E25-7X/6EG24N9ETK4/M - Bosch Rexroth R900977994

4WRZ10E25-7X/6EG24N9ETK4/M feeds the pilot stage internally and lets it drain internally as well. The valve therefore needs no extra pilot lines as long as enough pressure stands in the main gallery. Nominal flow is 25 l/min.

Advantages

• Internal pilot oil supply and internal pilot oil return, no extra lines required
• 25 l/min nominal flow at up to 170 l/min maximum flow
• Symbol E, three switching positions, four ports
• Maximum operating pressure 315 bar, NBR seals, HL hydraulic fluid
• 7.8 kg mass, concealed auxiliary actuation
• Electrical with external electronics, 24 VDC supply voltage

Application

Pilot-operated proportional directional valve in size 10 to connection diagram ISO 4401-05-05-0-05. Control is handled by external amplifier electronics at 24 VDC and the power connector is a 7-pole (6 + PE) type to EN 175201-804. Sufficient pressure in the P gallery is the precondition for the pilot stage to switch reliably.
