Abstract

This valve is of the type that comprises a tubular body (1), inside which an obturator (8) stressed elastically towards its closure position can be displaced axially. Said obturator has a rear pin (7) whereby it is guided via a tubular bush (6) slipped over said pin and coupled removably, via radial arms (5), in the mouth (3) of the body (1) via which the fluid exits. The bush (6) has, towards the mouth (2) of the body (1) via which the fluid enters, an extension (6') that ensures perfect guiding of the obturator (8) in addition to delimiting the travel thereof towards its open position, and the arms (5) are joined, via the end opposite that which joins to the bush (6), to a ring (4) that is threaded on the outside for coupling into the mouth (3), the pin (7) of the obturator (8) having, for its part, at least one longitudinal recess (7') in its cylindrical surface for evacuation of impurities from the valve.
