The Alfa Laval LKC-2 non-return valve (check valve) prevents the reverse flow of fluids and is specially designed for use in stainless steel pipe installations. LKC-2 Non-return valves are highly reliable check valves that ensure single-directional product flow through process lines. This protects process equipment that can be affected by reverse flow and prevents pressure surges and/or system shutdown.
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.
Internal surface finish: Bright (polished), Ra < 0.8 µm
