Globe valve is also called ball valve. It is mainly used to cut off the flow of media and can also adjust the flow rate. It can be divided into three types: straight-through type, right-angle type and direct-flow type.
The working principle of the stop valve is that the valve disc moves vertically along the center line of the valve seat, relying on the spinning of the valve stem thread to make the valve disc sealing surface closely fit the valve seat sealing surface, thus cutting off the flow of the medium.
The advantages of the stop valve are simple manufacturing, low price, and easy maintenance of the sealing surface. The disadvantages are that the installation length is large, the resistance to medium flow is large, and the sealing performance is poor.
The connection between the stop valve and the pipeline can be a threaded connection or a flange connection.
