ABSTRACT:
A float controlled valve assembly in which the valve is located in spaced relationship to the float with vent means being provided in between and above the level of a liquid receiving tank to provide an anti-siphoning arrangement. The valve is operated by an actuator which is suspended independently of the float but is movable in response thereto. The actuator is supported and guided for both axial and rotational movement which maintains friction between the actuator and the float at a minimum and also minimizes and maintains uniform and minimum wear between the co-acting valve parts.
