<p>The fluid flow control valve comprises a main body (1) in which are made two fluid pressure tappings (10). These tappings are connected respectively to upstream and downstream of a calibrated part (15) to form upstream and downstream pressure tappings. The calibrated part is formed by a piece connected in the main body to ensure the interface between the two pressure tappings and its calibrated orifice (17,25). It also connects without mixing the upstream and downstream calibrated part to the upstream and downstream pressure tappings.</p> |
