LKC Non-Return Valve

LKC Non-return ValveConcept

Spring loaded non-return valve.

Working principle

This non-return valve is intended for use with the aseptic sampling bottle for aseptic applications. It allows steam and CIP (Cleaning in Place) fluid to pass through the upper connection piece on the sampling valve and prevents back flow.


How It Works


The Alfa Laval LKC-2 non-return valve consists of an upper valve body, lower valve body, valve plug, seal ring, and guide disc. The valve body is assembled by means of a clamp and hygienically sealed with a special seal ring. A guide disc and four legs guide the spring-loaded valve plug with an O-ring seal. LKC-2 has welding ends for ISO or DIN connections.

Working principle

The spring acts on the valve plug, keeping the valve closed until the force from the pressure in the inlet exceeds the force of the spring. If a reverse flow should occur, the spring force and the pressure from the outlet will keep the valve closed.
