Feature | DANA CETOP Valves and blocks – Directional control

The use of solenoids with wet armatures allows a very prectical, safe construction completely dispensing with dynamic seals;the solenoid tube is screwed directly onto the valve chest whilst the coil is kept in position by means of a lock nut.
The special, precise construction of the ports and the improvement of the spools enables relatively high flow rates to be accommodated with a minimal pressure drop (∆p).
The centre position is obtained by means of calibrated length spring which reposition the spool in the centre or end of travel position once the action of the impulse is over.
