    Abstract: A float valve (10) is provided for use with a liquid medium, the float valve having an upright configuration and an inverted configuration. The float valve includes: a housing (12), defining at least one inlet port (20) and at least one outlet port (24); a float assembly (60) movable within the housing; and an auxiliary float member (50) movable within said housing. The float assembly (60) comprises a primary float member (70; 70′), different from the auxiliary float member, and a spring element (80). The primary in float member is configured for closing the at least one outlet port when in abutment therewith, the spring element being configured for providing a biasing spring force to the primary float member in a direction towards said at least one outlet port. The auxiliary float member is configured for providing a net upthrust force with respect to the liquid medium under submerged conditions irrespective of whether the float valve is in said upright configuration or in said inverted configuration.
