Butterfly valve series
Butterfly valve, also called flap valve, is a simple structure of the regulating valve, can be used for low-pressure pipeline media switch control of the butterfly valve is the closing member (valve flap or butterfly plate) for the disc, rotating around the valve shaft to achieve the opening and closing of a valve. Valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil, liquid metal and radioactive media. In the pipeline mainly plays a cutting off and throttling role. Butterfly valve opening and closing member is a disc-shaped butterfly plate, in the valve body around its own axis rotation, so as to achieve the purpose of opening and closing or regulation.
Ball Valve Series
Ball valve (ball valve), the opening and closing member (ball) driven by the stem, and rotational movement around the axis of the ball valve valve. It can also be used for fluid regulation and control, including hard seal V ball valve with a strong shear force between the V-shaped ball core and the metal seat of the welded carbide, especially for media containing fibers, tiny solid particles, etc.. The multi-way ball valve in the pipeline not only can flexibly control the media merging, diverging, and switching of flow direction, but also can close any channel and make the other two channels connected. This type of valve in the pipeline should generally be installed horizontally. Ball valve is divided into: pneumatic ball valve, electric ball valve, manual ball valve according to the drive mode.
Gate Valve Series
Gate valve (gate valve) is an opening and closing member gate, the direction of movement of the gate is perpendicular to the direction of the fluid, gate valve can only be fully open and fully closed, not for regulation and throttling. The gate valve is sealed by contact between the valve seat and the gate plate, usually the sealing surface will be welded metal materials to increase wear resistance, such as welded 1Cr13, STL6, stainless steel, etc. There are rigid gate and resilient gate, according to the gate, the gate valve is divided into rigid gate and resilient gate valve.
