The opening and closing parts of the manual stop valve are gate valves. The fitness direction of the gate valve is perpendicular to the liquid direction. The stop valve can only be fully opened and fully closed, and can not be adjusted or throttled. The gate valve has two raised faces. The gate valve of wedge-shaped stop valve can be made into a whole, which is called rigidity gate valve. It can also be made into a gate valve which can cause a small amount of deformation, so as to improve its process performance and fill the error caused by the raised face angle in the production process. This kind of gate valve is called ductility gate valve.
According to the raised surface, it can be divided into wedge gate flat type stop valve and parallel plane gate flat type stop valve. Wedge gate flat plate stop valve can be divided into: single gate pole type, double gate flat plate type and extensible gate flat plate type; parallel plane gate flat plate stop valve can be divided into single gate flat plate type and double gate flat plate type. According to the division of the external thread part of the valve seat, it can be divided into Non rising stem globe valve and Non rising stem gate valve.
