Proportional Directional Valve 4WRZE10W8-50-7X/6EG24N9ETK31/A1V - Bosch Rexroth R900925011

Test rigs for suspension components replay recorded travel profiles in which amplitude and frequency change constantly. The 4WRZE10W8-50-7X/6EG24N9ETK31/A1V follows the 10 V bipolar command at 50 l/min rated flow and 315 bar maximum.

Benefits

• Voltage command value 10 V bipolar, fed straight from the rig controller.
• 50 l/min rated flow, flow up to 170 l/min, operating limit 315 bar.
• Spool symbol W8 with blocked centre, three switching positions.
• Internal pilot oil supply and internal pilot oil return, without a pressure reducing valve.
• Concealed manual override, 7.96 kg, size 10 to ISO 4401-05-05-0-05, FKM seals.

Application

Suspension, damper and component test rigs use the valve in the position loop. The blocked centre holds the specimen in place if the signal fails, which protects the set-up. For larger cylinders the series offers 85 l/min rated flow.
