ABSTRACT:
The valve comprises a rotating operating wheel (32) acting on a closing element (20) inside the body (10) of the valve. In order to enable the wheel (32) to be operated easily and at the same time to prevent accidental opening, the wheel (32) is connected to the closing element via a ratchet system (34) with sawteeth which are oriented so as to prevent the closing element (20) from opening without prior axial displacement of the wheel (32) counter to the action of a spring (44).
