A device and method for a circulating valve for an actuator (1) supplied with pressurized fluid via a directional valve (10) and a first connecting pipe (A) to a first pressurized fluid chamber (4) and a second connecting pipe (B) to a second pressurized chamber (8), respectively, where the introduction of pressurized fluid in one of the pressurized fluid chambers (4, 8) causes the operative member (6) of the actuator (1) to be displaced towards a corresponding extreme position, and where a bypass valve (12, 14) controlled by the operative member (6) is connected in a communicating manner between the connecting pipes (A, B), the bypass valve (12, 14) being arranged so as automatically to open a connection between the connecting pipes (A, B) when the operative member (6) is in a specific position. |
