Production introduction
Foinbo® Swing check valves are an essential component of various applications where it is critical to prevent backflow. Their simple yet effective design allows for smooth operation, low maintenance, and reliable performance. These valves work by allowing flow in one direction while preventing flow in the opposite direction, protecting the system from contamination or damage.
One of the significant advantages of foinbo ® swing check valves is their versatility. They can function in both horizontal and vertical pipelines and can be installed in various flow directions, making them suitable for a wide range of applications. Whether you need to regulate the flow of water, gas, oil or chemicals, swing check valves have got you covered.

FAQ
Q: What is the swing check valve?
A: Swing check valve is a type of valve used to control the flow of fluid in a pipeline. It works by allowing fluid to flow in one direction and preventing backflow in the opposite direction, keeping the system safe and efficient. The valve is designed with a hinged disc that swings open when fluid flows in the correct direction and closes when there is a backflow of fluid, preventing any damage or contamination to the system.
Q: How to size a swing check valve?
A: In order to properly size a check valve, you must determine the minimum velocity required to fully lift the disc. Then find the mean velocity of flow in the piping system and ensure it is greater than or equal to the minimum required velocity.
Q: Where should a swing check valve be installed?
A: A swing check valve should be installed wherever backflow can contaminate media or damage system parts.
Q: Should swing check valve be vertical or horizontal?
A: A swing check valve can be mounted horizontally or vertically if the flow is coming from the bottom. However, the vertical orientation will cause a higher cracking pressure due to the weight of the flap.
Q: What's the difference between a check valve and a swing check valve?
A: A swing check valve uses a flapper that 'swings' off the seat to allow forward flow and then swings back onto the seat when the flow is stopped. In contrast, a spring loaded check valve incorporates a spring to assist in closing the valve.
