Product Description
The stop valve (Globe Valve) is a plug shaped disc with a flat or conical sealing surface, and the disc moves in a straight line along the centerline of the valve seat.
The movement form of the valve stem, (common name: non rising stem), also known as the lifting rotating stem type, (common name: rising stem) globe valve refers to a valve where the closing part (valve disc) moves along the centerline of the valve seat.
According to the movement of the valve disc, the change in the valve seat opening is directly proportional to the valve disc stroke.
Due to the relatively short opening or closing stroke of the valve stem and the highly reliable cut-off function, as well as the proportional relationship between the change of the valve seat opening and the stroke of the valve disc, this type of valve is very suitable for regulating flow.
Therefore, this type of shut-off valve is very suitable for cutting, regulating, and throttling purposes.
Stop valve, also known as cut-off valve, is the most 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 pressures, but also for high pressures.
The closing principle of a shut-off valve is to rely on the pressure of the valve stem to tightly fit the sealing surface of the valve disc and the sealing surface of the valve seat, preventing the flow of medium.

Shut-off valve
The shut-off valve only allows one-way flow of medium and has directional installation. The structural length of the shut-off valve is larger than that of the gate valve, and the fluid resistance is high. Therefore, the sealing reliability is not strong during long-term operation.
