Globe valve
Aug 03, 2018

The shut-off valve, also called the door, is the most widely used type of valve. It is popular because of the small friction between the sealing surfaces during the opening and closing process. It is relatively durable, the opening height is not large, and the manufacturing is easy. Convenient, not only for medium and low pressure, but also for high pressure. The closing principle of the shut-off valve is that, relying on the pressure of the valve bar, the sealing surface of the valve disc and the sealing surface of the valve seat are closely fitted to prevent the medium from flowing.

The valve plays an important role in the cutting and throttling of the medium in the pipeline in which it is located. The shut-off valve is an extremely important type of shut-off valve. The seal is applied by applying torque to the valve stem, and the valve stem is oriented in the axial direction. The valve disc applies pressure so that the disc sealing surface fits snugly against the seat sealing surface, preventing the medium from leaking along the gap between the sealing faces.
