VALCO GROUP check valve, also known as a non-return valve or one-way valve, is a mechanical device used to ensure the flow of fluid or gas in a system occurs in only one direction. It allows the medium to flow in one direction and prevents backflow or reverse flow in the opposite direction.
The primary function of a check valve is to allow fluid or gas to flow freely in one direction while preventing reverse flow. It acts as a barrier that opens under forward flow pressure and closes tightly when the flow direction reverses, creating a seal and preventing backflow.
There are different types of VALCO GROUP check valve :
- Swing Check Valve : It has a hinged disc that swings open to allow flow in one direction and swings back to close and prevent backflow.
- Ball Check Valve : It consists of a floating ball that moves in response to fluid pressure. When the pressure exceeds the backflow pressure, the ball lifts, allowing flow, and settles back to its seat to block reverse flow.
- Lift Check Valve : It utilizes a guided disc or piston that moves vertically within the valve body. The flow lifts the disc, allowing passage, and when flow stops or reverses, the disc seats to stop backflow.
- Inline Check Valve : It is a simple, spring-loaded check valve with a poppet or disk that opens against the spring force during forward flow and closes when flow reverses.

Check valve for industrial application
Check valves find widespread use in various industries and applications, including plumbing systems, oil and gas pipelines, water treatment plants, chemical processing, HVAC systems, power generation, and many more. They are crucial for maintaining system efficiency, preventing damage from reverse flow, and ensuring the safety of equipment and processes.
