What are Ball Valves? Working Principle, Advantages and Precautions for Use.

Ball valves are a common type of valve in life and are mainly used for fluid regulation and control. According to the working conditions, ball valves can be equipped with different driving devices to form a variety of different control methods, such as electric ball valves, pneumatic ball valves, hydraulic ball valves, and the like.

Working principle:

The Ball valve uses a hollow, perforated and pivoting ball to control flow through it.The Ball Valve2

The ball valve drives the valve handle to rotate by a transmission, which in turn drives the ball to rotate about an axis perpendicular to the flow. It is open when the ball’s hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle.

The Ball Valve


1 The structure is simple, the weight and volume are relatively small, and it is easy to disassemble and repair.

2 Since the valve stem only rotates, the packing seal of the valve stem is not easily broken, and the sealing capacity increases as the medium pressure increases.

3 The fluid resistance is small, and the full-bore ball valve has substantially no flow resistance. Pneumatic ball valves are one of the least fluid resistances in all valve classifications.

4 The operation is simple and rapid, and it only needs to be rotated by 90° from full opening to full closing, which is convenient for long-distance control.

5 It is suitable for a wide range of applications, from a few millimeters to a few meters, from high vacuum to high pressure.

The working principle of the sanitary ball valve is similar to that of the ordinary ball valve, mainly because the production materials and the manufacturing process are more strict. If you want to have a deeper understanding of sanitary valves, please visit our website for more information.

Precautions for use

1 The ball valve must be cleaned and repaired once a year.

2 The ball valve should be activated at least once a month to prevent the ball from getting stuck.

3 The ball valve can only be fully open or fully closed and cannot be used for throttling.

Founded in 2002, Adamant Valves, as a global sanitary valves manufacturer and valves supplier, has grown to become one of the leading valves manufacturers for high precision stainless steel sanitary valves, pumps and pipe fittings.
