Middleeast Valve is leading Swing check valve supplier Saudi Arabia. Which Supplies different types of valves to cites and countries like Saudi Arabia, Iraq, Madinat Zayed, Ruwais. Swing check valve is a type of valve that allows fluid to flow in only one direction. It consists of a hinged disc or plate that swings open when fluid flows in the desired direction, and closes when fluid tries to flow in the opposite direction. The swing check valve is typically used in pipelines to prevent backflow and protect equipment from damage. It is often found in systems that transport water, oil, gas, and other fluids. Some common features of swing check valves include a spring or weight to help close the valve, a connecting flange or flanged ends for easy installation, and a corrosion-resistant material to ensure long-lasting performance.
PARTS
- Body: The main component of the valve that houses all the other parts.
- Disc: A movable part that is attached to the hinge and moves to open or close the valve.
- Hinge: A pivot point that allows the disc to move freely and open or close the valve.
- Seat: A surface on the body of the valve where the disc seals against to prevent flow.
- Springs: Used to provide a closing force on the disc to ensure it seals properly against the seat.
APPLICATION
Swing check valves are used in piping systems to allow flow in one direction and prevent flow in the opposite direction. They are often used in systems where there is a possibility of backflow, such as in sewage systems or irrigation systems.

CHECK VALVE
Middleeast Valve is well known Check valve Supplier in UAE. A check valve is a circulating device which is commonly used in pipeline systems to permit a fluid to flow in just one direction and avoid backwash or backflow. They can be applied to a wide range of fluids, including liquids, gases, condensate, and slurries.
It has two slots, one for input and other for output.
It is also called ‘One-way valve', ‘Clack valve' or ‘Non-return valve' since it only allows media to flow in one direction. Fluids enter the valve at the inlet under pressure, where they push the disc away from the valve's seat and out the outlet.
The disc automatically returns to its seat to stop the flow if there is a pressure drop.
Industries where Check Valves used are :
- Chemical processing
- Power generation
- Hydropower
- Petrochemical
- Oil and gas
- Gas plants
- LNG
- Liquid gases
- Refineries
- Petrochemical
- Chemical and many more industries …
Types of Check Valves-
- Swing Check Valve
- Wafer Check Valve
- Ball Check Valve
- Lift Check Valve
- Dual Plate Check Valve
- Silent Check Valve
- Non-slam Swing Check Valve
- Tilting disc Check Valve
- Pressure seal Check Valve
How does a Check valve Work ?
The operation of a check valve depends on pressure variation. When the output pressure increases, the check valve will close off, requiring high pressure on the input rather than the output. There are several closing mechanisms for different types of check valves. They typically serve to prevent backflow To ensure that waste water leaves the system and does not return, check valves, for instance, are installed in sewer pipes. They come in a range of sizes, varieties, and styles depending on the needs.
Advantages of Check Valves-
• Self-actuated
• Fast-acting
• It maintains the pressure
• Prevent water hammer.
• Maintenance costs are decreased.
• Capable of adapting to varying flow conditions
Difference between swing and wafer check valve
Wafer check valve
The wafer-thin construction of wafer check valves gives them their name. These slim valves are designed to fit between two flanges in confined places. This valve doesn't have any controls. The valve's central swinging disc, which opens in one direction and closes if liquids flow back in the other direction, is its essential part.
Swing check valve
Swing check valves are used for swinging disc to allow or block flow. The two differ in the way their bodies are made. In contrast to the wafer check valve, swing check valves are not intended for extremely small places. Around the spot where the disc opens up, their bodies have been formed.
