Hydraulic pilot solenoid valve
200 l/min, max 315 bar | WL 4.16 KRACHT

A pilot valve operates the main control valve electrohydraulically. For operating the pilot valve, pressure-tight direct and alternating current magnets can be fitted switching in oil. The control piston for the main control valve is operated by the flanged pilot valve directly subject to actuating pressure and switched to indexing position a or b.

The buncher space or spring chamber is formed by two flanged covers that can also be fitted with a stroke limiter. The control oil in- and outlet can be individually switched to internal or external.

The main control valve is available in the following control piston feedback models:
Pilot valve Main control valve
1. Spring-centred central position - Spring-centred central position
2. Spring-centred final position - Without spring return
3. Without spring feedback - Without spring return
4. With locking final position - Without spring return
Actuating pressure is required with model 4 for fixing the final position of the main control valve.
