Swing Check Valve
A swing check valve ensures one-way flow by using a disc that swings on a hinge to allow fluid in and automatically closes to prevent backflow. It protects pumps and motors from reversal and prevents leakage. The valve features an internal swing arm structure, with a spherical joint connecting the arm and disc for slight positional adjustments. Available in various sizes and flange configurations, swing check valves are essential for preventing backflow and ensuring controlled fluid movement in systems.

- A swing check valve is equipped with a single disc. Under the force of the flowing medium, the disc automatically opens or closes around a fixed hinge pin. When the medium stops flowing, the disc closes under its own weight. The entire operation process is automatic and requires no manual intervention.
- KOSEN swing check valves feature a simple structure, fewer components, convenient maintenance and repair, and a low failure rate. A full-open disc design is adopted to provide a larger flow area after the disc opens, resulting in low fluid resistance and a high flow coefficient.
- A counterweight or damping structure can also be applied to reduce water hammer impact during disc opening and closing.
- Check valves are installed in pipelines to prevent reverse flow of the medium and to ensure one-way flow within the piping system only.
» Spiral wound gaskets are standard for Class 150 to Class 600 valves, while ring joint gaskets are standard for Class 900 and above valves, or available as an option for Class 600 valves upon customer request.
» The hinge and hinge pin are designed and mounted to allow full movement of the disc.
» A renewable seal-welded seat with Stellite 6 hard facing is provided as standard, while a screwed-in seat is available as an option.
» The standard swing disc type is suitable for horizontal installation in liquid service applications, or for vertical installation where the liquid flows from bottom to top.
» Standard bosses are provided for drain tapping at location “G” on the lower part of the body centerline. Additional bosses can be supplied according to customer requirements.
