product description
Check valves are crucial types of valves in industrial systems. Their primary function is to prevent the back - flow of media, ensuring the safe and stable operation of the system.
A common type is the swing check valve. It has a swingable disc. When the media flows in the forward direction, the disc is pushed open, allowing the media to pass through. However, when there is a tendency for the media to flow back, the disc quickly closes under the action of gravity and the reverse pressure of the media to prevent back - flow.
The double - disc check valve consists of two semi - circular discs. When the fluid flows forward, the discs open and the fluid passes smoothly. Once the fluid tries to flow in the reverse direction, the two discs close rapidly. This structure makes the double - disc check valve small in size, light in weight and easy to install.
Check valves are widely used in fields such as water supply and drainage, and petrochemical industry, safeguarding the normal operation of various systems.
