The difference between check valve and globe valve
different types
Globe valve, also known as cut-off valve, is a mandatory sealing valve. When the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak;
Check valve refers to a valve whose opening and closing part is a circular disc and acts by its own weight and medium pressure to block the backflow of the medium. It is an automatic valve.
Check valve and globe valve, one is an automatic valve, and the other requires pressure.
different uses
Check valve refers to the valve that automatically opens and closes the valve flap by relying on the flow of the medium itself to prevent the backflow of the medium, also known as check valve, one-way valve, reverse flow valve, and back pressure valve. The check valve is an automatic valve whose main function is to prevent the backflow of the medium, prevent the reverse rotation of the pump and the driving motor, and discharge the medium in the container
The globe valve is used to cut off and adjust the flow. Due to the small friction between the sealing surfaces during the opening and closing process, it is more durable, the opening height is not large, it is easy to manufacture, and it is convenient to maintain. It is not only suitable for medium and low pressure, but also suitable for high pressure. The closing principle of the globe valve is to rely on the pressure of the valve stem to make the sealing surface of the valve disc and the sealing surface of the valve seat closely fit to prevent the flow of the medium.
