Stainless steel gate valves are used in many pipes, stainless steel, and the corrosion resistance is very good. Stainless steel gate valves can be divided into wedge gate gate valves and parallel gate gate valves according to the sealing surface configuration. The wedge gate valve can be further divided into: single gate type, double gate type and elastic gate type; parallel gate type gate valves can be divided into single gate type and double gate type. According to the thread position of the valve stem, it can be divided into two types: open gate valve and dark gate valve.
Stainless steel gate valves should generally be installed horizontally in the pipeline. When the gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the ram is pressed against the valve seat on the other side by the medium pressure to ensure the sealing of the sealing surface, which is self-sealing. Most stainless steel gate valves use forced sealing, that is, when the valve is closed, the external force is forced to press the gate to the valve seat to ensure the sealing of the sealing surface.
