Speciality Valve is the leading Check Valve Manufacturers in India, offering quality solutions engineered for high reliability and long life in aggressive applications. Check valves are integral components of piping systems where prevention of backflow is very critical.
Check Valve:
A non-return valve or a check valve is employed to allow flow of fluid in one direction and one direction only. It works by itself to prevent backflow, protecting pumps, compressors, and other machinery from being damaged by back pressure.
Why Required?
Check valves are essential within fluid systems wherein fluid must be allowed to flow in one direction only to avoid contamination, system failure, or damage. They have widespread applications in water systems, oil and gas pipelines for transportation, as well as processing plants.
Main Components of Check Valve:
· Valve Body: Accommodates internal parts and fluid passage of flow.
· Disc or Ball: Equates to opening or closing the passage based on direction of flow.
· Seat: Forms a seal to prevent reverse fluid flow.
· Spring (optional): Assists in closing quickly in some designs.
· Cover: Allows access for inspection and maintenance.
Working of Check Valve:
When the fluid flows in the correct direction, it pushes the disc or ball off the seat, allowing flow. When reversed flow occurs, the disc returns to the seat due to gravity or spring pressure, not allowing the fluid to back up. This self-actuating action results in smooth, automatic operation.
Benefits of Check Valve:
· Automatic reverse flow prevention
· Preserves pumps and pipelines from damage
· Does not require external control
· Low maintenance
· Simple installation and compact design
