An actuated ball valve is a type of quarter-turn valve which uses a hollow, perforated, and pivoting ball to control flow through it. It is operated by a motor or air (pneumatic actuator), allowing for remote control and automation of valve operation.
Actuated ball valves work by rotating a ball with a hole through its centre, 90 degrees around its axis. When the ball's hole is in line with the flow, it is open, and when it's perpendicular, the flow is blocked.
Actuated ball valves offer high durability, reliability, and are suitable for on/off and control applications. They provide tight sealing with low torque and are easy to operate, making them ideal for automated systems.
The most common types of actuation for ball valves are electric and pneumatic. Electric actuation uses motors, whereas pneumatic actuation utilises air pressure for operation.
Yes, actuated ball valves can be used for throttling applications. However, they are more suitable for on/off control. For precise flow control, other types of valves might be more appropriate.
Actuated ball valves are widely used in various industries, including water and wastewater management, oil and gas, chemical processing, and power generation, due to their efficiency and reliability.
Remote control of actuated ball valves is typically achieved through an electric or pneumatic actuator connected to a control system, which can be operated manually or automated based on process requirements.
Actuated ball valves are made from a variety of materials, including stainless steel, brass, and PVC, to suit different applications and fluid compatibility requirements.
Yes, actuated ball valves are designed to handle high-pressure applications. The choice of material and design will depend on the specific pressure and temperature requirements of the system.
Selecting the right actuated ball valve involves considering factors such as the type of fluid, pressure and temperature range, actuation method, and material compatibility. Consulting with valve specialists or manufacturers is recommended for optimal selection.
Maintenance for actuated ball valves can be more complex than manual valves due to their mechanical and electrical components. Regular checks are needed for the actuator mechanism, electrical connections, and the valve itself. However, the advantage of actuated valves is less wear and tear from manual operation, potentially leading to longer service life.
Safety considerations for actuated ball valves include ensuring proper installation and regular maintenance to prevent leaks and failures. It's also crucial to use valves that are rated for the specific pressure and temperature conditions of the application. Additionally, implementing fail-safe mechanisms, like fail-closed or fail-open settings, can prevent accidents in case of power loss or actuator failure.
