A ball valve is a quarter-turn valve that uses a rotating ball with a hole to control the flow of fluid through a pipeline.
ReadBall valve (ball valve), a valve that is driven by a valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids. The hard-sealed V-ball valve has a strong shear force between the V-shaped core and the metal valve seat of the hardfacing. It is especially suitable for fibers and small solid particles And other media. The multi-port ball valve can not only flexibly control the confluence, divergence, and flow direction of the medium on the pipeline, but also can close any channel and connect the other two channels. This type of valve should generally be installed horizontally in the pipeline. Ball valve is divided into pneumatic ball valve, electric ball valve and manual ball valve according to the driving mode.
The gate valve is a gate of the opening and closing piece. The movement direction of the gate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted and throttled. The gate valve is sealed by the contact between the valve seat and the gate. Usually, the sealing surface will be welded with metal materials to increase wear resistance, such as 1Cr13, STL6, stainless steel and so on. The gate has rigid gate and elastic gate. According to the different gates, the gate valve is divided into rigid gate valve and elastic gate valve.
