Pressure stage control valves
The DV S pressure stage control valve is a pilot-control pressure relief valve with several parallel pilot valves set at two different pressures. The pressure stage switch valve has an integrated directional control valve. This valve is used to switch different pressure stages (upstream pressure) on and off. The control oil drain is internal or external.
A typical application is clutch control in ship gearboxes.
