Check valves are designed to prevent backflow of the medium in the pipeline. They are automatic self - acting devices, passing the medium in one direction and blocking its flow in the opposite direction.
According to the principle of operation, check valves are divided into lift (code 16) and rotary (code 19). Lift valves are simpler and more reliable. They can be angular and straight - through. Check valves are available in various sizes. In terms of replacement, there is no limitation to installing a larger valve instead of a smaller valve being replaced.
When choosing replacements, you should pay attention to the fact that most of the check valves are used on the suction lines of pumping units. They allow the pumps to be started without pre - priming the pump, since the check valve prevents the liquid from draining from the suction line.
