Proportional Directional Valve 4WRZE25E1-325-7X/6EG24ETK31/A1D3V - Bosch Rexroth R901272135

When system pressure moves, the pilot supply of a pilot-operated valve moves with it. The 4WRZE25E1-325-7X/6EG24ETK31/A1D3V has the pressure reducing valve built in and meters flow at a nominal 325 l/min steadily up to 350 bar.

Benefits

• Pressure reducing valve built in - the pilot circuit stays independent of system pressure up to 350 bar.
• 325 l/min nominal flow, with a maximum of 870 l/min through the valve.
• Symbol E1 in size 25 with three switching positions and four ports.
• Command value ±10 V on 24 VDC, on-board electronics, 7-pole connector (6 + PE) to EN 175201-804.
• ISO 4401-08-08-0-05 interface, 20.58 kg, FKM seals for HL fluid.

Application

The valve drives large cylinders and hydraulic motors in presses, rolling mills and test rigs where speed and direction are set continuously. Internal pilot oil supply and internal pilot oil return save the external X and Y lines. UKCA conformity for electromagnetic compatibility is declared.
