LKUV-2 Air-Relief Valve
Alfa Laval LKUV-2
Air-Relief Valve
The Alfa Laval LKUV-2 is a reliable, self-acting Air-Relief Valve that vents excess air from process pipelines, or Pumps to prevent cavitation and the negative effects of air entrainment. Vertically installed, it is ideal in places where air needs to be removed to maintain design pressure conditions, like at the top of a pipeline, or the suction side of a Pump inlet pipe to remove excess air before starting the Pump.
This self-acting Relief Valve is designed for air-venting duties in hygienic applications across the Dairy, Food and Beverage industries, among many others. It is typically used in Cleaning-in-Place return line (CIP-R) applications.

LKUV-2 Air-Relief Valve Key Features
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 90°C (194°F).
How the LKUV-2 Air-Relief
Valve Works
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 equalised, the ball is reseated on the lower Valve seat, thus closing the Valve.
