Swing Check Valve

ALIS Valves offers Swing Check Valves for industrial applications requiring reliable non-return flow control and protection against reverse fluid flow. These valves use a hinged disc that swings open when fluid flows in the intended direction and closes when the flow slows, stops or reverses. This automatic operation helps prevent backflow and protects pumps, pipelines and connected equipment from potential damage. Depending on the valve design and operating conditions, Swing Check Valves can provide low flow resistance when fully open and are available in different sizes, pressure ratings and body materials to suit various piping systems.

Swing Check Valves are suitable for applications in water treatment plants, oil and gas facilities, power generation units, chemical processing plants, wastewater systems and industrial fluid distribution networks. They can be used with compatible liquids, gases or other process media according to the valve’s design specifications. Important selection factors include operating pressure, temperature, flow rate, fluid characteristics, valve size, disc and seat materials, installation orientation and end connection type. Selecting the appropriate valve configuration helps support dependable backflow prevention, efficient fluid movement and reliable performance under the intended operating conditions.
