<p>Regulating valve (10) comprising:
- a body (11) crossed by a channel (12) for a fluid,
- a shutter (13) sliding in the body (11), according to a sliding direction (A), between a closing position and an opening position. The shutter (13) protrudes along the sliding direction (A) between a back end (16) and a front end (17), which is provided with a side surface (18) parallel to the sliding direction (A) and coupling with the internal surface (15) of the seat (14). The front end (17) is tubular and has at least one aperture (20) crossable by a fluid according to a normal direction to the sliding direction (A). The aperture (20) has two sides (20a, 20b) which join together to form a cuspid and diverge along the sliding direction (A).</p> |
