The general ball valve does not indicate the direction and can be installed casually. It is reasonable to say that the ball valve has no direction, but in actual installation, in order to prevent excessive leakage between the valve body and the valve cover, the ball valve body is generally connected to the direction of the tank or material. Some ball valves are directional, generally there are marks of direction on the ball valve, if it was installed conversely, then will achieve a bad seal results. The ball valve is divided into a one-way sealing ball valve and a two-way sealing ball valve. The former has directionality. If the installation is reversed, the sealing under the complete pressure difference cannot be guaranteed, and the latter has no directivity. If the manual ball valve is not oriented, but if it is also control valve, it is directional. V-type ball valves and eccentric hemisphere valves are directional, and generally the medium flow direction mark is marked on the valve body. The floating ball valve and the fixed ball valve are two-way, and the eccentric hemispherical valve, the V-shaped ball valve, and the poppet-type track ball valve are unidirectional. The ball valve has an O-ball valve and a V-ball valve.
Ball valve (the ball valveshould be a stop valve in the oceaneering andship domain fields), refers to a kind of valve which open or close by turning the ball with a hole on it. The standard GB/T21465-2008 "Valve Terminology" is defined as: the opening and closing member (sphere) is driven by the valve stem and rotates around the square ball valve as the axis for rotary motion. It can also be used for the adjustment and control of fluids. The hard-sealed V-ball valve has a strong shear force between the V-shaped core and the metal seat of the hard facing alloy. It is especially suitable for fiber-containing, tiny solid particles medium. The multi-way ball valve not only can flexibly control the switching of the merge, split, and flow directions of the medium, 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 classification: pneumatic ball valve, electric ball valve, manual ball valve.
