A ball valve consists of a valve body, a perforated ball, and a rotating mechanism for operating the ball. The diameter of a hole in the ball matches the pipe. When the ball is rotated to align the hole with the streamline, the fluid can flow freely; when the ball is rotated 90 degrees and the hole is perpendicular to the streamline, the fluid flow is cut off.
The design of the angle valve is more special. The valve body is roughly L-shaped, so that the fluid needs to change the flow direction inside the valve. Angle valves usually contain a plug or conical valve disc, which is opened or closed by rotating the handwheel to raise and lower the valve disc.
Ball valves use the aperture in the rotating ball to achieve switching and flow control. Ball valves can switch from fully open to fully closed very quickly, which makes them very suitable for cutting and dispensing applications.
Angle valves adjust the position of the valve disc by rotating the handwheel to control the amount of fluid passing through the valve. Generally, angle valves are used for more precise flow control, especially in occasions where regulation or frequent valve operation is required.
Due to its fast switching characteristics, ball valves are usually used in situations where fluids need to be quickly cut off. In addition, ball valves perform well in terms of pressure resistance and temperature range and are widely used in industries such as petroleum, natural gas, chemicals, and papermaking.
Angle valves are commonly found in household and industrial water supply systems, HVAC systems, and various occasions with specific flow requirements. With its ability to provide precise flow control, angle valves are particularly suitable for application scenarios that require delicate adjustments.
The advantages of ball valves include simple structure, easy maintenance, good sealing performance, and easy and fast operation. Its main disadvantage may be that in some applications that require fine flow control, ball valves may not be as accurate as other types of valves.
The advantage of angle valves is that they can provide precise flow control, especially for applications that regulate flow. The disadvantage may be that their structure is relatively complex, maintenance costs are high, and they may not be as durable as ball valves in high temperature and high pressure environments.
