The Larox Automatic Changeover (LAC) valve operates on the discharge side of two pumps in parallel. Both pumps can run simultaneously or independently. When one pump is switched off, the ball will automatically drop back stopping the back flow to the other pump. It is particularly suited for mill cyclone feed pumps. As the elastomer covered ball moves, it rotates with the flow. This ensures that the valve self cleans and permits it to open and close reliably even under severe conditions of slurry build up.

The valve body is carbon steel (fabricated) and can be lined in linatex, natural black, neoprene, hypalon, E.P.D.M rubber, ceramic or urethane. The ball is replaceable and made of urethane or rubber and is available in different sizes.

The valve offers considerable flexibility, being flanged to customer specification. Shouldered end connections can be made available for Victaulic couplings if required. The valve body and face-to-face dimension can be changed to suit existing applications.

Other features include:

• Pressure drop is minimal – pressure ratings – 150, 240 and 365 psig.
• Flushing port in ball body
• Replaceable seats
• Lifting lugs
• Different mounting brackets can be fitted to suit application.
