Contact usHow Do Alfa Laval Control and Check Valves Work?
Alfa Laval control and check valves are engineered to meet diverse application needs, offering reliable flow management for liquids, gases, and air. The valves open when the pressure and flow of the process fluid exceed the opposing pressure exerted on the valve mechanism. Depending on the design, this mechanism may include free-moving polypropylene balls, alternating seats, or a stainless steel spring that holds the valve in position.
When the pressure on one side becomes greater, the valve mechanism closes, effectively stopping the flow of process liquid, air, or gas. This precise control ensures safe, efficient, and reliable operation, safeguarding your processes and equipment.
