LKUV-2 air-relief valves are designed for use when removal of air from a process line without loss of product is a primary concern. The LKUV-2 air-relief valve helps to control the air in your system. The LKUV-2 is a reliable, automatic air-relief valve that is installed vertically on the top of a pipeline or container—or before the inlet for a pump—where the removal of air is required. These provide solid safety, efficiency and low cost of ownership for processing where hygiene standards are essential.
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.

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.
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.
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 90°C (194°F).
The Alfa Laval LKUV-2 air-relief valve consists of an upper valve body, lower valve body with welding stub, seal ring and polypropylene ball. The valve body is assembled by means of a clamp.
These automatic double-seat air-relief valves have a lightweight, freely moving polypropylene ball that closes against the upper or lower seat, depending on pressure conditions.
When air pressure increases, the ball is forced off its seat, allowing excess air pressure to be vented to the atmosphere. When pressure is equalized, the ball is reseated on the lower valve seat, thus closing the valve.
The LKUV-2 allows air to vent out of a system when installed vertically on the top of a pipeline or container or before the inlet for a pump. The valve allows the venting of excess air pockets, such as in the following examples:
Bleeding a pipe line where an air pocket has formed as a result of the installation. In this case, the valve is installed at the top of the pipe.
Bleeding a pipe on the suction side of a pump. The suction side is bled automatically, before the pump starts, establishing a vacuum. The air relief valve will prevent air from binding to the product, which prevents the subsequent cavitation. In this case the valve is installed in front of the pump, on top of the inlet pipe.
The valve body is in two parts and is assembled by means of a clamp. The lower valve body has a welding stub.
