Abstract

See full text

The present disclosure is directed to a combination air valve that uses buoyancy to lift seals into place, preventing media from escaping from the valve. Once the seals are in place, pipeline pressure is used to open and close the valve. The combination air valve includes a low flow vent configured with a pressure equalizing configuration allowing for reduced extrusion forces along the low flow vent, allowing vertical movement of a float shaft at high valve gas pressures with reduced forces.
