An axis that draws 220 l/min still has to be controlled at the full 350 bar without the valve becoming a weight problem. This pilot-operated size 25 4WRDE weighs 16.94 kg and passes up to 870 l/min at peak. The command reaches the on-board electronics as a 4 to 20 mA current signal.

Not every application needs 500 l/min, but many need the full 350 bar. This size 25 4WRDE proportional directional valve meters 220 l/min nominal at operating pressures up to 350 bar and lets up to 870 l/min pass for short periods.
Benefits
- 350 bar operating pressure at 220 l/min nominal, the full pressure rating in the smaller size 25 body.
- Up to 870 l/min maximum flow leaves headroom for rapid traverse and regenerative circuits.
- Spool symbol V with a linear characteristic and internal position feedback for exact spool openings.
- At 16.94 kg it is easy to fit and to swap during a service window.
- ISO 4401-08-08-0-05 pattern with subplate mounting for standard interfaces.
