Non-return valve preventing the reverse flow of fluids

Benefits :

• Durable
• Self-operating valve
• Simple to set up
•  Keeps process equipment safe
•  Keeps backflow from occurring

LKC non-return valve for sanitary industry applications :

• Process security that is both safe and dependable
  • Count on the dependable Alfa Laval LKC-2 Non-return valves to maintain a unidirectional flow of products in your process lines. This safeguards process equipment from reverse flow, which can cause pressure surges and system failure.
• Discontinued valve selection
  • Standard 304 or acid-resistant 316L stainless steel is used to create the Alfa Laval LKC-2 non-return valves. These simple-to-install valves can withstand temperatures between -10°C and 140°C (EPDM) and a maximum product pressure of 10 bar. You may get these check valves with a semi-bright or polished finish, and they come with a number of welding ends for ISO or DIN connections, so they’re really versatile.

Construction

The Alfa Laval LKC-2 non-return valve consists of upper and lower valve bodies, valve plugs, seal rings, and guide discs. A clamp holds the valve body in place, and a specific seal ring keeps it hygienically sealed. An O-ring-sealed, spring-loaded valve plug is guided by a disk and four legs. LKC-2 can be fitted with ISO or DIN welding ends.

Working Principle

The valve remains closed due to the spring’s action on the valve plug until the force of the incoming pressure exceeds the spring’s force. The valve will remain closed in the event of reverse flow due to the combined efforts of the spring and outlet pressure.

Options

Rings of wet product sealant constructed of NBR or FPM
