<p>The invention relates to a valve (A) intended to be mounted on a receiving unit (B) in order to limit the pressure of a fluid, including at least one cap piece (6), one end (7) of which is designed to be fixed to the unit and nearby bearing a diaphragm (membrane) (15) of a single piece with a valve shutter (16) interacting with a seat (5) produced in the unit, an operating knob (9) joined to the cap piece in the region of the opposite end (8) of the cap piece from the membrane, means (18, 21) for joining the valve shutter (16), the cap piece (6) and the knob (9), and an elastic calibration member (23). This modular precalibrated or calibratable valve includes an annular retaining member (17) fixed into the cap piece (6), and the perimeter of the diaphragm (15) is immobilised between a stop piece (14) formed in the cap piece and this retaining member; one of the joining means is a through-rod (18). <IMAGE></p> |
