Total price
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.
