The working principle of commonly used check valves: safeguarding your fluid safety
In fluid control systems, check valves are essential components. They act as faithful guardians, silently protecting the safety of the fluid and preventing backflow. Today, we will unveil the working principles of four such "guardians": brass check valves, silent check valves, rubber flap check valves, and swing check valves.

Selection techniques, installation, debugging, and troubleshooting of double-disc check valves
Check valves are valves that open when the flow in the pipeline is in the forward direction and close when it is reversed. They are mainly used to prevent the backflow of media, prevent pumps and drive motors from reversing, and prevent the release of media in containers; currently, commonly used check valves are swing check valves where the valve disc rotates around the valve body pin, and lift check valves where the valve disc moves along the vertical centerline of the valve body.

Introduction and working principle of a vertical check valve
A vertical check valve is a common industrial valve whose main function is to prevent backflow of media in a piping system. A vertical check valve is a valve that prevents backflow of the media; it has a vertical structural shape. It mainly consists of a valve body, valve cover, valve disc, and spring, etc. When the media flows in the normal direction, the valve disc will be pushed open by the media, allowing flow; while when the media flows in reverse, the valve disc will be closed by the reverse pressure of the media, preventing backflow.
