Check valves restrict fluid flow in one direction. Check valves have two ports, one for the media inlet and one for the media output. They’re known as ‘one-way valves or ‘nonreturn valves’ since they only allow media to flow in one direction.
Principle of working
A minimum upstream pressure is required to open check valves in Dubai and allow flow through them. The ‘cracking pressure’ of check valves is the lowest upstream pressure at which the valve opens. The cracking pressure varies depending on the valve design and size. The valve will close if the upstream pressure drops below the cracking pressure or if there is back pressure. The closing mechanism of check valves in the UAE might vary depending on their design.
Types of check valves
Swing check valve
To allow forward flow, the swing valve has a disc that rotates on a hinge on the valve seat. It swings back into position to prevent reverse flow when the flow ceases. Swing check valves in Dubai have less turbulence and a lower pressure drop than other types of check valves.Wafer check valve
A tiny disc swings to block or allow flow through wafer valves. The disc closes to provide a seal to prevent backflow when the flow is in the opposite direction. Wafer check valves are appropriate for small pipe systems and systems that move solid or semisolid media because of their thin, short, and compact construction.Tilting disc check valve
In this valve, the pivot point of a tilting disc check valve is in the center of the disc, allowing fluid to flow over both the top and bottom of the disc. With low flow rates, it has a low-pressure drop, while with high flow rates, it has a high-pressure drop.Ball check valve
To close the opening, a ball check valve utilizes a free-floating or spring-loaded ball that sits on the sealing seat. The ball is dislocated from its seat and enables flow when the fluid pressure on the intake side exceeds the cracking pressure. When back pressure is applied, the ball will close either by itself or by using the spring, thereby closing the aperture.Duckbill valve
Duckbill valves allow fluid to flow through a soft tube with a naturally flattened end. The flow allows fluid to move through the flat end of the duckbill. The duckbill end returns to its flattened shape when pressure is released, effectively cutting off the flow. Due to the operation of check valves in the UAE, Obaid Masood Group, the top check valve supplier in the UAE, recommends employing them for all of the following reasons:- To prevent harm to equipment downstream from backflow
- To avoid pollution caused by reverse flow
- To avoid leeching
- To maintain a vacuum seal
Advantages of check valves
- Serve as a safety and backup system
- Compatible with horizontal and vertical use
- Fast-acting
- Reduce downtime and production losses
- Reduced maintenance expenses
- Few mechanical parts
- Reduced footprint
- Adaptable to varying flow conditions
- Not requiring electricity to function
