What are the differences between ball valves and angle valves?
The main difference lies in their functions. Ball valves cannot change the direction of water flow, while angle valves can. They also differ in flow resistance; generally, angle valves have slightly higher flow resistance than ball valves, primarily due to their different structures. Therefore, for the same diameter, ball valves have a slightly larger flow capacity.
1. Design Structure
Ball Valve: The valve core is a ball with a central hole. It is opened and closed by rotating a handle; water flows in and out directly.
Angle Valve: The valve body is L-shaped, with the inlet and outlet at a 90-degree angle. It can change the direction of water flow. Internally, it usually has a plug or a conical valve disc.
2. Working Principle
Ball Valve: Controls on/off by rotating the ball. It opens and closes quickly but cannot finely adjust the flow rate. The valve core is easily damaged when partially open.
Angle Valve: Adjusts the flow rate by raising and lowering the valve disc. Suitable for frequent operation and precise control.
3. Application Scenarios
Ball Valve: Suitable for applications requiring rapid shut-off, such as heating inlet pipes and gas water heaters (requiring high-flow ball valves).
Angle Valve: Commonly found in washbasins, toilets, and hot/cold water inlet pipes of water heaters, where adjustment or maintenance isolation is required.
