Abstract
The valve includes a disk (8) one side of which is subjected to the action of an adjustable thrust unit and the other side of which is applied against a seat (3) connected to the pressure source of said hydraulic installation, the thrust unit (12) being constituted by an adjustably pressurized deformable chamber. The valve is used in particular for protecting hydraulic installations e.g. water pipes against accidental overpressures, e.g. water-hammer.
