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.

Cómo funciona
Construcción
La válvula antirretorno Alfa Laval LKC-2 consta de un cuerpo superior, un cuerpo inferior, un obturador, un anillo de sellado y un disco guía. El cuerpo de la válvula se ensambla mediante una abrazadera y se sella de forma higiénica con un anillo de sellado especial. Un disco guía y cuatro patas guían el obturador accionado por resorte, que cuenta con un sello de junta tórica. La LKC-2 dispone de extremos para soldar para conexiones ISO o DIN.
Principio de funcionamiento
El resorte actúa sobre el obturador de la válvula, manteniendo la válvula cerrada hasta que la fuerza ejercida por la presión en la entrada supere la fuerza del resorte. En caso de que se produzca un flujo inverso, la fuerza del resorte y la presión de la salida mantendrán la válvula cerrada.
Options
- Product wetted seal rings in NBR or FPM
