LKUV-2 Air-relief Valve

Reliable air relief valve
Alfa Laval LKUV-2 air-relief valves are automatic double-seat valves engineered to relieve excess air in industrial processing lines, thus preventing the negative effects of air entrainment. Vertically installed, LKUV-2 air-relief valves are ideal for use on the top of a pipeline or container or before a pump inlet, where the removal of air is required to maintain design pressure conditions.

Improved processing efficiency
LKUV-2 air-relief valves help improve processing efficiency. By preventing air entrainment, the valves contribute to product integrity, energy efficiency and protection of pipelines and pump stations against the effects of pressure surges and water hammer.

LKUV-2 air-relief valve range
With a sturdy, bright finish stainless steel construction, the standard range of Alfa Laval LKUV-2 air-relief valves is available in various dimensions to meet most requirements. These valves are designed for maximum product pressure of 10 bar and temperatures up to 90ºC (194ºF).


    • Improve processing efficiency
    • Stainless steel construction
    • Reliable air relief valve

    LKUV-2 is a double-seated valve with a freely moving plastic ball. The ball, which is lighter than water, closes against the upper or lower seat, depending on the pressure conditions. 

    The valve body is in two parts and assembled by means of a clamp. The lower valve body has a welding stub.

    Testimonial from VP Antibody Manufacturing

    “This pump cut our processing time from 3 days to 1 shift. I’m not giving this pump back. You will have to come and get it if you want it... and that won’t likely happen.”
