The process of controlling the opening and closing of a valve, typically through mechanical or electrical means. Actuation can be manual or automated, depending on the application and requirements.
Characteristics
– Types of Actuation:
– Electric: Uses electric motors to operate the valve.
– Pneumatic: Utilizes compressed air to move the valve.
– Hydraulic: Employs pressurized fluid to control the valve.
– Response Time: The speed at which the valve can open or close, which is crucial in many applications.
– Control Options: Can be controlled remotely or locally, allowing for flexibility in operation.
– Power Source: Different actuation methods require different power sources, influencing installation and operational costs.
Examples
– An electric solenoid valve that opens when an electrical current is applied, commonly used in automated systems.
– A pneumatic valve actuator that controls the flow of air in a manufacturing process, allowing for quick adjustments.
– A hydraulic actuator used in heavy machinery to manage fluid flow and pressure effectively.
