Origin:

The quality magnetic check valve is used to prevent the backflow of the medium; the globe valve is used to cut off the circulation of the medium, and can also be used to adjust the flow.
The specific differences between quality magnetic check valve and globe valve are:
One: different types
The globe 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;
Quality magnetic check valve refers to a valve whose opening and closing parts are circular discs and act by its own weight and medium pressure to block the backflow of the medium. It is an automatic valve.
Quality magnetic check valve and globe valve, one is automatic valve, one needs to apply pressure.

Two: different uses
Quality magnetic check valve refers to the valve that automatically opens and closes the valve flap by relying on the flow of the medium itself, and is used to prevent the backflow of the medium. The medium discharge 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. Quality magnetic check valve 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.
