Valve Size
Concept
Alfa Laval non-return valve LKC-2 is designed for use in stainless steel pipe installations to prevent reverse flow.

Working principle
LKC-2 opens when the pressure below the valve plug exceeds the pressure above the plug and the spring force. The valve closes when pressure equalization has been achieved. A higher counter pressure will press the valve plug against the seat.

Standard Design
The valve body is in two parts, assembled by means of a clamp ring 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.The valve is available with welding ends for tubes according to ISO and DIN 11850.

Pressure
Max. product pressure: . . . . . . . . . . 145 PSI (10 bar)
Mechanical
Required differential pressure for opening the valve when fitted in a vertical pipe, as shown in fig. 3, is approx. 0.41 PSI (0.06 bar)
