Single Seat Valves & Double Seat Valves
Alfa Laval’s range of single seat valves consists of large numbers of purpose-designed valve units that are very robust and flexible. They are ideal for use in processes with a high hygiene standard.
On the other hand, double seat valve concept provides modular solutions that are easily tailored to any specific requirement. The double seat design provides long-lasting, spillage-free operation thus minimizing the risk of product contamination. The use of double lip seals provides added protection to ensure safe and hygienic operation.

Proven shut-off valve
The Alfa Laval LKAP seat valve is a quality pneumatic shut-off valve that is based on reliable, proven technology. It is ideal to handle small flow rates of up to 9 m3/h and purpose-built for specialty applications, such as a CIP supply valve to Unique mixproof valves or dosing valves in mixing applications.
Clean simplicity
Like all other hygienic Alfa Laval valves, the LKAP features a simple, straightforward design with the fewest possible components and minimal moving parts. Smooth surfaces and sanitary finishes contribute to good hygiene and cleanability.
Shut-off valve range
The standard Alfa Laval LKAP valve is a normally closed (NC) valve with a two- or three-port valve body (LKAP-V and LKAP-T, respectively). Upon request, the LKAP valve is also available as a normally open (NO) valve.
Compliance with most hygienic standards
Alfa Laval LKAP valves meet most standards requested in the dairy, food and beverage, and personal care industries
Concept
The LKAP pneumatic valve is a remote-controlled shut-off valve, widely
used for small flows and for dosing applications in food, chemical and
other industries.
Working principle
The valve is operated by means of compressed air and has spring
return. It has few and simple moving parts which results in a very
reliable valve.
Standard Design
LKAP consists of actuator with air cylinder and piston, double lipseal
for stem, stem unit with replaceable O-ring in the plug, and valve body
with welding connections. It has visual indication of the valve position
and is available with 2 (LKAP-V) or 3 ports (LKAP-T). A reed switch unit
for indication of open and closed positions is available. The valve can
be ordered as normally open (NO) or normally closed (NC) versions.
NC is standard.
The LKAP valve come in DN/OD 25 mm.
The LKAP valve come in DN/OD 1”.
