An actuated valve is a valve that is operated by an external power source, such as an electric motor, pneumatic actuator, or hydraulic actuator. This allows for remote or automated control of the valve’s position. On the other hand, a gate valve is a type of valve that uses a gate or wedge to control the flow of fluid. It is typically operated by a manual handwheel or wheel handle to open or close the valve. In summary, the main difference between an actuated valve and a gate valve is the method of operation. An actuated valve is operated by an external power source for remote or automated control, while a gate valve is typically operated manually using a handwheel or wheel handle.

Your talking about two different things. A gate valve is a type of valve while an actuated valve refers to a control method.

A gate valve is simply a type of valve that uses a gate disc that stops flow through the valve. It is the most common type of valve in industrial plants.

Technically all valves are actuated. But for all intents and purposes, an actuated valve is any valve opened or closed by a form of power. For example, while we can say manually actuated valve, an actuated valve can be controlled electrically, hydraulically, or pneumatically, or a combination of the above.

So long story short. A gate valve refers to type of valve, while actuated refers to how the valve is opened or closed. There are many more classifications of valves, and when your ordering one, the valve description on its own can be a paragraph long.
