Gate valve: There is a flat plate in the valve body that is perpendicular to the flow direction of the medium, and the plate is lifted and lowered to achieve opening and closing.
Features: Good airtightness, small fluid resistance, small opening and closing force, wide application, and certain flow regulation performance, generally suitable for large-diameter pipes.
Ball valve: A sphere with a hole in the middle is used as the valve core, and the opening and closing are controlled by rotating the sphere.
Features: The structure is simpler than the gate valve, the volume is small, the fluid resistance is small, and it can replace the function of the gate valve.
Butterfly valve refers to a valve whose closing part (valve disc or butterfly plate) is a disc, which rotates around the valve axis to achieve opening and closing.
Features: Simple structure, small size, light weight, suitable for making valves with larger diameters. It can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.
The valve plate of the butterfly valve and the valve core of the ball valve both rotate around their own axis;
The valve plate of the gate valve moves up and down along the axis;
The butterfly valve and gate valve can adjust the flow rate by the degree of opening; it is not easy to do this with the ball valve.
