A stop valve is a type of valve used in plumbing and fluid control systems to regulate the flow of liquids or gases. It can be fully opened or closed to either allow or stop the passage of fluid. Stop valves are commonly found in residential and commercial plumbing, as well as in industrial applications, to control water flow and ensure system safety.
By properly installing and using the check valve, you can effectively prevent the backflow of the medium, protect the system equipment and maintain the system pressure, and ensure the safe and stable operation of the pipeline system.
Check valves are very important in pipelines because they prevent the backflow of media, protect system equipment and maintain system pressure.
The core steps of testing the function of a check valve include: sealing performance test, opening and closing test, pressure level test and reverse flow test.
The core elements to consider when choosing a check valve that suits your needs are: material, caliber, sealing method, installation location and applicable occasions.
After installation, a test is required to ensure that the check valve is working properly. Open the valve of the pipeline system, check whether the check valve effectively prevents backflow, and observe whether it is.
