A check valve restricts fluid flow in one direction. They 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 a check valve and allow flow through it. The check valve’s ‘cracking pressure’ 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 a check valve might vary depending on its design.
Due to the operation of check valves, Obaid Masood group recommends employing them for one of the following four 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
- Reduce downtime and production losses
- Reduced maintenance expenses
- Few mechanical parts
- Reduced footprint
- Adaptable to varying flow conditions
- Not requiring electricity to function
