Alfa Laval LKC
Applying the Alfa Laval LKC-2 Check Valve
The Alfa Laval LKC-2 Check Valve is a widely used valve and has proven itself in places where the back flow of fluids must be prevented. It has a two-part housing which are connected by a clamp ring. The valve opens at a pressure of 0.06 bar and then has a minimum pressure drop. The operation of the non-return valve is based on a spring construction and close off on a standard EPDM gasket. Alternatively an NBR or Viton sealing set available. The house is made of 316L stainless steel and can be ordered as a conduit. The LKC-2 is available from DN25 - DN100 and 1 "-4" (OD).
Alfa Laval check valve LKC-H is a horizontal version of the LKC-2. An eccentric reducer at the outlet makes it a self draining check valve. Also the LKC-H is used after pumps to help the regulating of the flow.
