LKAP Air-Operated Valve
Valve type LKAP-T.

Application

The LKAP pneumatic valve is a remote-controlled shut-off valve, designed for 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.

Materials

Product wetted steel parts: 1.4404 (316L).
Other steel parts: 1.4301 (304).
Rubber: EPDM rubber or Nitrile (NBR).
Finish Semi bright
