Ball valve and gate valve are the same type of valve, the difference is that its closing member is a sphere. In meantime the sphere around the valve body centerline for rotation to achieve opening or closing a valve. The Flange ball valve, as one of the type of ball valve, is mainly used for cutting off, distributing. Z pewnością, changing the flow direction of the medium in the pipeline is also the important circle.

The material of Flange Ball Valve

Flange ball valve products can be made of various standard materials, such as carbon steel and stainless steel. These materials are widely used because of their resistance to temperature and corrosion. Jednakże, flanged ball valves made of polymer materials have shown greater durability than other types of ball valves when used in aggressive applications. Tymczasem, as experted and trusted Valve manufactuer in China, We ensure quality valves with raw-material. So a quality supplier also should be considered.

Ball valve is a new type of valve widely used, which has the following advantages:

1. Opór płynu jest niewielki, and its resistance coefficient is equal to that of pipe sections of the same length.
2. Simple structure, small volume and light weight.
3. It is tight and reliable. The sealing surface material of the ball valve is widely made of plastic, with good sealing performance. It has also been widely used in the vacuum system.
4. It is easy to operate and can be opened and closed quickly. Only 90 ° rotation is required from full opening to full closing, which is convenient for remote control.
5. It is easy to maintain, the ball valve is simple in structure, the sealing ring is generally movable, and it is convenient to disassemble and replace.
6. When the valve is fully opened or closed, the sealing surfaces of the ball and valve seat are isolated from the medium. When the medium passes through, it will not cause erosion of the valve sealing surface.
