Abstract

Disclosed is a valve for activation of hydraulic cylinder, in particular corner cylinder of powered support unit at underground building works. The valve has at least one valve piston that closes the through channel in the valve, at that the through channel (48, 50) does not pass through the valve piston (40), and the valve has an element (P1) for connection to recirculation line (R) which during long time is connected to the valve piston (40). To decrease forces that act on seat of the valve, the valve piston (40) is at both sides connected to connection element of the recirculation line. The invention provides for a method for the installation of powered support unit by means of the valve.
