LKUV-2 Air-relief Valve
The Alfa Laval LKUV-2 is a reliable, self-acting air relief valve that releases excess air from process pipelines, or pumps to prevent cavitation and product loss, thereby preventing the negative effects of air entrainment. Vertically installed, it is ideal for use where the removal of air is required to maintain design pressure conditions, such as at the top of a pipeline, or pump inlet pipe on the suction side to remove excess air before starting the pump.
Air relief valve designed for solid safety, efficiency and low cost of ownership
- Improved processing efficiency and product integrity
- Enhanced energy efficiency
- Protects pumps against the risk of cavitation
- Low total cost of ownership
This self-acting air relief valve is designed for air-venting duties in hygienic applications across the dairy, food, beverage and many other industries. It is typically used in Cleaning-in-Place return line (CIP-R) applications.
How does the LKUV-2 air relief valve work
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 automatic air relief valve 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 automatic air release valve 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 90°C (194°F).

Construction
The automatic air relief valve consists of an upper valve body, lower valve body with welding stub, seal ring and polypropylene ball. The relief valve air body is assembled by means of a clamp.
Operating principle
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.
Options
- Seal ring in NBR (Buna N) or FPM (SFY)
