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”.
