A gate valve system to control fluid flow includes a valve body having a bore which fluid can pass through. The system includes the valve body and the valve body has the bore to allow penetration of the fluid, and a cavity formed by an inner wall of the valve body substantially in parallel is included. The system includes a gate and at least one end of the gate is formed by a radial rim portion. The system includes a bonnet connected to be removed on the surface of the valve body, and one part of the inner side of the bonnet includes a curved surface adapted to correspond to at least one end of the gate formed by the radial rim portion. The system is operatively positioned on the gate by a through-hole on the bonnet, and includes an operation mechanism connected to be removed. |
