A Swing Check Valve is a mechanical valve that allows the flow of fluid in one direction only and automatically prevents backflow by using a hinged disc or flap. The disc swings open to allow the fluid to pass through the valve, and swings closed when the flow stops or reverses, effectively blocking backflow. This type of valve is typically used in pipelines where reverse flow could cause damage or system malfunctions, such as in water and sewage treatment, as well as in heating and cooling systems. The swing check valve is simple in design, reliable, and widely used in various industries.
