non return valve

Non-return valves facilitate unidirectional flow of mediums by preventing reversed flow due to pressure conditions within pipes. These valves are integral for maintaining the correct direction of fluid movement in systems. Various types, such as spring-loaded, swing type, and clapper type valves, cater to different applications like ensuring proper operation in heating and cooling systems or preventing backflow in domestic water systems. However, flow through these valves can result in a significant pressure drop that needs consideration during system design.
