Proportional Directional Valve 4WRZE10W8-25-7X/6EG24N9ETK31/F1V - Bosch Rexroth R900958853

Anyone calibrating force transducers or cylinders wants to see scatter in the specimen, not in the actuator. The 4WRZE10W8-25-7X/6EG24N9ETK31/F1V works at 25 l/min rated flow and 315 bar maximum with a current command value that stays stable across the whole test set-up.

Benefits

• Current command value 4...20 mA, insensitive to voltage drop on long measuring cables.
• 25 l/min rated flow for fine graduation, flow up to 170 l/min.
• Spool symbol W8 blocks at centre, three switching positions, operating limit 315 bar.
• Internal pilot oil supply and internal pilot oil return, without a pressure reducing valve.
• Concealed manual override, 8.68 kg, size 10 to ISO 4401-05-05-0-05, FKM seals.

Technical data

Application

Calibration and force test rigs, valve test benches and laboratory set-ups use this valve as their actuator. The blocked centre freezes the specimen in place if the signal fails. For faster cycles the series offers 50 and 85 l/min rated flow.
