What is the difference between a ball valve and an angle valve?

The terms "ball valve" and "angle valve" are sometimes used interchangeably, but it's important to note that there can be a distinction based on the context and the specific design of the valves being referred to. Let's explore the potential differences:

Ball Valve:

Design:

A ball valve has a spherical-shaped disc (the "ball") inside the valve body. The ball contains a hole through its center, and when the valve is open, the hole aligns with the pipe to allow fluid flow.

Operation:

Ball valves are typically operated by turning a handle or lever 90 degrees. When the handle is perpendicular to the pipe, the valve is closed; when parallel, it's open.

Flow Control:

Ball valves provide a straight-through flow, offering minimal resistance to fluid flow. They are often used in applications where quick on/off control is needed.

Applications:

Commonly used in various industries, including water supply lines, gas lines, and industrial processes.

Angle Valve (Angle Stop Valve):

Design:

An angle valve, or angle stop valve, is characterized by its L-shaped or right-angle design. The inlet and outlet of the valve are positioned at a 90-degree angle.

Operation:

Similar to ball valves, angle valves are operated by turning a handle. The handle is typically located at the top of the valve, and turning it controls the flow of water.

Flow Control:

Angle valves provide a 90-degree turn to control the flow of fluid. They are often used in situations where space is limited or where a more compact design is needed.

Applications:

Commonly used in household plumbing for connecting appliances and fixtures like toilets, sinks, and faucets. The right-angle design allows for easy installation in confined spaces.

In summary, while both ball valves and angle valves are types of valves used to control the flow of fluids, the key differences lie in their specific designs and applications. Ball valves are characterized by a spherical mechanism and straight-through flow, while angle valves have a right-angle design and are often used in household plumbing for space efficiency. The distinction may vary based on regional terminology and industry practices. Always refer to specific product specifications to understand the characteristics of a particular valve.
