Introduction To LKUV-2 Air-relief Valve Control-Check valves

The Alfa Laval LKUV-2 stands as a dependable, self-acting air relief valve designed to release excess air from process pipelines or pumps. This functionality prevents cavitation and product loss, effectively mitigating the adverse effects of air entrainment. Installed vertically, it proves ideal for situations where the removal of air is crucial to maintain design pressure conditions. This includes scenarios such as at the top of a pipeline or the pump inlet pipe on the suction side to eliminate excess air before initiating pump operations.

Low total cost of ownership

LKUV-2 Air-relief Valve How It Work

The Alfa Laval LKUV-2 Air-relief Valve is an air-relief valve with a free moving polypropylene ball, which is lighter than water. The polypropylene ball alternates between two seats depending on pressure conditions on the inlet. When the pressure on the inlet increases, the ball is forced off the lower valve seat and moves to the upper seat, thereby closing the valve against the atmosphere. If air enters the system, the pressure is reduced, thereby moving the ball away from upper seat and venting excess air to the atmosphere. If there is no pressure or vacuum in the system, the ball alternates to lower position thereby closing the valve.
