Proportional Directional Valve 4WRZE10W8-50-7X/6EG24N9EK31/F1V - Bosch Rexroth R900971168

In a foundry the valve sits next to hot tooling and still has to meter evenly. The 4WRZE10W8-50-7X/6EG24N9EK31/F1V handles 50 l/min rated flow at 315 bar maximum there, works with FKM seals and accepts the command as a 4...20 mA current signal.

Benefits

• FKM seals and a 4...20 mA current command value, matched to warm and electrically noisy surroundings.
• 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 with external pilot oil return, without a pressure reducing valve.
• Concealed manual override, 11.25 kg mass, size 10 to ISO 4401-05-05-0-05.

Application

Die adjustment, core pull axes and ejectors on die casting machines are the field of use. The external pilot oil return keeps the pilot stage clear of back pressure when several consumers discharge into the tank at once. Smaller axes run at 25 l/min.
