When backflow is not an option - Swissfluid check valves reliably keep process media in the intended flow direction. They open when the flow is forward and close automatically when the differential pressure drops or the flow reverses - without additional actuation or control.
In this way, they prevent unwanted backflow, protect important system components and contribute to stable and safe processes.
Coordinated lining and material combinations as well as different designs enable targeted adaptation to the application. Whether ball check valve or check valve - Swissfluid also offers suitable solutions for corrosive, solids-laden and abrasive media.
A check valve is an automatic valve that allows the flow of a medium in only one direction and prevents unwanted backflow. The valve opens due to the flow of the medium and closes automatically as soon as the flow direction changes or there is no longer sufficient differential pressure.
Check valves protect pumps, pipelines, and other system components against backflow and potential damage. They help make processes safer, prevent operational interruptions, and ensure stable system operation.
Swissfluid check valves are suitable for demanding applications involving corrosive, abrasive, or aggressive process media. They are used in sectors such as the chemical, pharmaceutical, petrochemical, and paper industries, as well as other process industries where high standards of resistance and reliability are required.
Ball check valves use a movable ball as the shut-off element and are particularly suitable for applications involving challenging media and requiring reliable sealing. Tilting-disc check valves operate using a hinged disc that is opened by the flow and closes upon flow reversal. The appropriate design depends on the requirements of the specific application.
Depending on the application, various materials and linings are available to ensure optimal resistance to the specific process medium. These include, among others, high-quality linings such as PFA and other media-resistant materials. The selection is based on the medium, temperature, pressure, and the specific requirements of the system.
