A check valve, also known as a non-return valve or one-way valve, is a mechanical device used in fluid systems to allow flow in only one direction and prevent backflow or reverse flow. The primary function of a check valve is to ensure that fluids or gases flow through a pipe or duct in a single direction, preventing them from flowing backward.
Operation:
When fluid or gas flows in the desired direction ( forward flow ), it exerts pressure on the movable component, pushing it open and allowing the fluid to pass through the valve unhindered. However, if flow tries to reverse direction ( backflow ), the movable component is forced closed by the pressure of the fluid or by gravity, preventing the backflow from occurring. The design of the check valve ensures that the force required to open the valve in the forward direction is lower than the force exerted by the fluid in the reverse direction, thus allowing for efficient operation. South American Valve are a leading Check valve manufacturers in Brazil. It typically consists of a body with inlet and outlet ports, and a movable component such as a disc, ball, or flap that is pushed open by forward flow and closes under the influence of reverse flow or back pressure. Check valves are commonly used in a variety of applications and industries.
Types:
Swing Check Valves
Tilting Disk Check
Disk Check Valves
Wafer Check Valves
Piston Check Valves
Benefits:
Prevents backflow and contamination of fluid or gas supply.
Helps maintain system efficiency by ensuring flow direction control.
Reduces the risk of damage to equipment and pipelines caused by reverse flow.
Can be used in both horizontal and vertical piping systems. Requires minimal maintenance due to simple design and operation.
