[Overview] 

 The forged steel flange gate valve belongs to a forging gate valve. The opening and closing part of the gate valve is the gate plate. The movement direction of the gate plate is perpendicular to the fluid direction. The gate valve can only be fully open and closed, and cannot be adjusted and throttling. According to the configuration of the sealing surface, it can be divided into wedge gate valves and parallel gate valves. Most gate valves are forced sealed, that is, when the valve is closed, external forces are forced to press the gate to the seat to ensure the sealing of the sealing surface. 

 [Features] 

 A. The fluid resistance is small, and the sealing surface is less eroded and eroded by the medium. 

 B. It is more labor-saving to open and close. 

 C. The flow direction of the medium is unrestricted, and it does not disturb or reduce pressure. 

 D. The shape is simple, the structure length is short, the manufacturing process is good, and the application range is wide.

Each process, each facility, and each environmental constraint has its own special requirements. Therefore, Dongyan offers a comprehensive range of products covering different performance levels, pressures, different functions and different materials.
