A Check Valve is a valve used to control the direction of flow of a liquid or gas and is designed to prevent backflow or reverse flow of fluid. A check valve is a valve used to control the flow of fluid in a pipeline and prevent fluid from flowing backwards or backwards. Its design principle is based on a simple concept: fluid can flow freely in one direction, but be hindered in the opposite direction. Here are some common check valve models:
One-way check valve: also known as a butterfly valve, it achieves one-way flow of fluid through a self-closing disc. Hemispherical Check Valve: A disc with a spherical shape that closes when the fluid flows in the opposite direction of the spherical shape. Poppet Check Valve: Uses a spring or gravity to close the disc, which is pushed up and closed when the fluid flows backwards. Suspension Check Valve: Similar to a lift check valve, but the disc is suspended in the fluid. Swing check valve: Control the one-way flow of fluid by rotating the disc. Diaphragm Check Valve: Using an elastic diaphragm as the disc, the diaphragm bends to close when the fluid flows backwards. Note that these are just some of the common check valve models, there are actually many other models and sizes available.

We also have Oxygen Sensor Spacer on sale, if you need it, please contact us. Check valves are widely used in many industries and fields, including water supply systems, drainage systems, chemical processes, oil and gas transmission, sewage treatment, etc. They play an important role in ensuring safe fluid flow and preventing backflow. The specific choice of which type of check valve should be evaluated according to specific application requirements, fluid properties and flow conditions, and a professional valve manufacturer or supplier should be consulted for the best advice.
