Ideal for hygienic applications, this valve ensures safe, high-quality product flow and is easy to install. Available in two versions: the LKC-2 for vertical flow and the LKC-H for horizontal flow. It is widely used in the dairy, food, beverage, brewery, and other process industries to ensure single-directional flow.

How does LKC Non-Return Valve work?
The LKC Non-return Valve operates based on pressure differentials. When the pressure at the inlet exceeds the force of the spring, the valve opens, allowing flow. If reverse flow occurs, the spring force and pressure from the outlet keep the valve securely closed. The minimum differential pressure required for the valve to open in a vertical pipe installation is approximately 6 kPa (0.06 bar).
