What is a Check valve?

A check valve is a type of valve used to control the flow of fluid in one direction. It automatically closes to prevent backflow of fluid. Check valves are commonly installed in piping systems and at the outlet of pumps to stop the flow when the pump stops or if there is a reverse pressure. This helps to prevent damage to the system and loss of efficiency. There are several types of check valves, including spring-loaded, weight-assisted, and butterfly types.

Application of Check valve

✅ Water Supply Systems
Check valves are used in water supply systems to prevent backflow, ensuring that contaminated water does not flow back into the clean water supply.
✅ Pump Systems
A check valve is installed at the outlet of a pump to prevent backflow of water or oil when the pump stops.
✅ Heating Systems
In heating systems, check valves are essential for preventing the backflow of cold water from the heating source.
