Proportional Directional Valve 4WRZE10W8-25-7X/6EG24N9ETK31/A1V - Bosch Rexroth R900977526

Motion platforms receive their signal every few milliseconds and answer any delay with visible lag. The 4WRZE10W8-25-7X/6EG24N9ETK31/A1V converts the 10 V bipolar command into up to 25 l/min rated flow at an operating limit of 315 bar.

Benefits

• Voltage command value 10 V bipolar, fed straight from the platform controller card.
• 25 l/min rated flow, flow up to 170 l/min, operating limit 315 bar.
• Internal pilot oil supply and internal pilot oil return, compact piping at the power unit.
• Spool symbol W8 with blocked centre, three switching positions.
• Concealed manual override, 8.48 kg, size 10, FKM seals, HL fluid.

Application

Simulators, vibration test rigs and positioning axes with a high signal rate work with this valve. As pilot supply and return are internal, the subplate alone is enough without extra lines. The same axis with a current signal carries the F1 code.
