ABSTRACT:
The high-pressure valve has a valve body defining an elongated longitudinal extension, delimiting a chamber and having an input port, which is defined on its lateral surface, and an output port, which is arranged on a first axial end thereof. The valve body supports, on a second end, a motor and a manual actuation member which can be connected, by virtue of coupling members, to a shaft for the actuation of a first bush accommodated within the chamber. The first bush is provided with actuation elements for the sealed non-rotational movement of adjustment pin which opens a connecting path between the input port and the output port. The adjustment pin engages in a neck located in the chamber and moves toward the output port, in order to open the connecting path, and in the opposite direction, in order to close it. Sensors are furthermore provided for detecting movement of the adjustment pin.
