How to distinguish between check valve and globe valve
date:2026-03-27 14:42
1、 Check valve
A check valve refers to a valve that automatically opens and closes the valve disc based on the flow of the medium itself, used to prevent the backflow of the medium. It is also known as a check valve, one-way valve, backflow valve, and back pressure valve. Check valve is an automatic valve, whose main function is to prevent medium backflow, prevent pump and drive motor from reversing, and prevent the release of container medium
2、 Globe valve
Globe valve, also known as shut-off valve, is a widely used type of valve. Its popularity is due to the low friction between the sealing surfaces during the opening and closing process, its durability, small opening height, easy manufacturing, and convenient maintenance. It is not only suitable for medium and low pressure, but also for high pressure. The closing principle of a globe valve is to rely on the pressure of the valve stem to tightly adhere the sealing surface of the valve disc to the sealing surface of the valve seat, preventing the flow of the medium.
Valves play an important role in cutting off and throttling the medium in the pipeline they are in. As an important cut-off valve, globe valves seal by applying torque to the valve stem, which is in the axial direction
