How does a non return valve work

Construction

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.

Safe and reliable process protection

Alfa Laval LKC-2 Non-return valves are highly reliable check valves ensure single directional product flow through process lines. This provides protection for process equipment that can be affected by reverse flow and prevents pressure surges and/or system shutdown. Engineered for hygienic applications, the Alfa Laval non return valve offers dependable flow control and protection against backflow in both vertical and horizontal installations.

Options

Product wetted seal rings in NBR or FPM.
