What is a swing check valve? How does it work?

A check valve is a type of valve that allows the flow of liquids or gases in one direction only. It prevents backflow and protects equipment from damage caused by backflow. Check valves are used in a variety of industries, such as plumbing, HVAC, chemical, oil and gas.

The basic principle of a check valve is simple. It consists of a flap or disc designed to open in one direction and close in the opposite direction. When the liquid flows in the right direction, the flap or disc is pushed open, allowing the liquid to flow through. However, if the liquid tries to flow in the opposite direction, the flap or disc is pressed against its seat so that the liquid cannot flow back.

There are several types of check valves, including swing check valves, tilting disc check valves and ball check valves. Each type works in a slightly different way, but uses the same basic principle of a flap or disc that opens and closes depending on the direction of flow of the liquid.

In summary, a check valve allows fluid to flow in one direction and prevents backflow in the opposite direction. It is a simple but essential component in many industrial processes and applications.

Wafer check valves applications

Wafer check valves are used to prevent the unwanted backflow of liquids or gases in pipelines. Here are some common applications for wafer check valves:

Water supply and wastewater disposal

Industrial process lines
Power plants
Chemical industry
Petrochemical plants
Food and beverage industry
Heating and cooling systems
Shipbuilding
Pharmaceutical industry
Swimming pools & more

The applications of wafer-type check valves are diverse, ranging from ensuring drinking water quality to ensuring safety and efficiency in industrial processes. They are critical components in many industries and applications where fluid flow control is essential.
