Globe Valve

The stem axis of the globe valve is perpendicular to the sealing surface of the valve seat. The stem of the globe valve generally rotates and lifts, and the handwheel is fixed on the top of the stem. When the handwheel is rotated in a clockwise direction, the thread of the valve stem rotates downwards, and the sealing surface of the valve disc is in close contact with the sealing surface of the valve seat, and the shut-off valve reaches the closed state; when the handwheel is rotated in the counterclockwise direction, the thread of the valve stem rotates upward, and the valve disc The sealing surface is separated from the sealing surface of the valve seat, and the stop valve is opened.

The opening or closing stroke of the valve stem is relatively short, and it has a very reliable cut-off action, making this valve very suitable for the cut-off or adjustment and throttling of medium. Once the disc of the shut-off valve is in the open state, there is no contact between its seat and the sealing surface of the disc, and it has a very reliable cut-off action. This kind of valve is very suitable for the cut-off or adjustment and throttling of the medium. .

The reason why the globe valve is so popular is that the friction between the sealing surfaces in the opening and closing process is small, it is relatively durable, the opening height is not large, the manufacturing is easy, and the maintenance is convenient. It is not only suitable for medium and low pressure, but also suitable for high pressure.
