<p>Disclosed is a gas purge valve that includes a housing formed with a fluid inlet and a fluid outlet. The fluid outlet is bounded by a kinetic valve seating, and a sealing assembly, which includes a float member coaxially displaceable within the housing, and a sealing cap coupled to said float member. The sealing cap is axially displaceable with respect to the float member between a first position in which it conjoins the float, and a second position in which it departs from the float. The sealing cap is formed at an outside face thereof with a kinetic seal fitted for sealing engagement of the kinetic valve seating, and an automatic valve aperture formed in the sealing cap and bounded by an automatic valve seating. An automatic sealing member articulated is at an upper end of the float member for sealing engagement of the automatic valve seating.</p> |
