A ball valve is a type of valve that uses a spherical disc, known as a ball, to control the flow of fluid through it. The ball has a hole or port through the center, allowing fluid to pass when the valve is open. When the ball is rotated 90 degrees, the port is perpendicular to the flow, effectively shutting off the flow.
Characteristics
– Quick Operation: Ball valves can be opened or closed with a quarter turn, making them easy to operate.
– Tight Seal: They provide a reliable seal, preventing leaks when closed.
– Durability: Made from robust materials, ball valves are designed to withstand high pressure and temperature.
– Versatility: Suitable for various applications, including water, gas, and oil.
Examples
– Full Port Ball Valve: This type has a ball with a hole that matches the pipe diameter, allowing for maximum flow.
– Reduced Port Ball Valve: The ball has a smaller hole, which can restrict flow but is often more compact.
– Trunnion Ball Valve: This design features a trunnion that supports the ball, making it suitable for high-pressure applications.
