Spill-resistant vacuum breaker valve
A spill-resistant vacuum breaker valve that includes a check assembly positioned in a valve body and is movable between an open position for allowing water to flow into the valve body through the water inlet and out of the valve body through the water outlet, and a closed position for preventing water from flowing out of the valve body through the water outlet. The check assembly cooperates with a float assembly movable by movement of the check assembly between an open position allowing air to enter the valve body through the air inlet and a closed position sealing the valve body against flow of air into the valve body through the air inlet. The float assembly is adapted to pivot sufficiently to level the float and seal against ejection of water from the valve in the event of non-axial movement of the check assembly in the valve body.
