An industrial Swing Type Check Valve is a valve used to control the flow of liquids and gases. Swing check valves are designed to open and close with the flow of the fluid. When the fluid flows in the direction that allows the valve to open, the disk will swing open, allowing the fluid to pass through. When the fluid reverses direction, the disk will swing closed, preventing the fluid from flowing back.
Swing check valves are designed for high-pressure applications and are often used in conjunction with other types of valves, such as relief and safety valves. Swing check valves are available in a variety of materials.
