Válvula anti-retorno LKC
Specially designed for use in stainless steel pipe installations, LKC-2 non-return valves prevent the reverse flow of fluids. Widely used in various processes throughout the sanitary industry, these standard non-return valves are safe and highly reliable.
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.
Non-return valve range
The standard range of Alfa Laval LKC-2 non-return valves are constructed of standard 304 or acid-resistant 316L stainless steel. Easy to install, the valves are designed to handle maximum product pressure up to 10 bar and temperatures ranging from -10°C to 140°C (EPDM). For added versatility, these check valves are available with either a semi-bright or polished finish, and a variety of welding ends for ISO or DIN connections.

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.
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.
- Product wetted seal rings in NBR or FPM
