Abstract

The valve (1) comprises a first hydraulic actuator (2) cooperating with a second hydraulic actuator (3), a casing (5) with a connection for a hydraulic fluid source, a tank connection (T) and a refill valve (23) for supplying fluid to the return side (4) of the first actuator. The casing also has a connection for a progressively increasing pilot pressure from the second actuator, a device cooperating with this pilot pressure and a means for opening a connection (23) between the pressure side (3) of the first actuator and the tank connection via this device once a pre-determined pilot pressure level has been reached.
