An actuated valve is like a switch for controlling the flow of liquids or gases in pipes. It can automatically open or close when you need it to, rather than someone doing it by hand. It's useful in many industries to control the movement of fluids in a precise and efficient way.

An actuated valve is a valve that uses an actuator to open or close automatically. A control valve, on the other hand, is a valve that can adjust the flow of a fluid continuously or incrementally.

An actuated valve is a type of valve that can be opened or closed automatically using an actuator. A solenoid valve, on the other hand, is a specific type of actuated valve that uses an electromagnetic coil (a solenoid) to control the opening and closing of the valve.

An air-actuated valve works by using compressed air to open or close the valve. It has an actuator, which is like a little machine that responds to signals or commands. When you send a signal to the actuator, it releases or pushes air to move the valve's mechanism, which can either open or close it.

In simple terms, a valve is a device that controls the flow of liquids or gases in pipes or systems by opening or closing, and an actuator is a device that operates the valve, making it open or close, usually in response to a signal or command.

A simple example of a self-actuated valve is a check valve. This type of valve automatically opens or closes in response to the flow of a fluid in one direction, without the need for an external power source or control system. It allows the fluid to flow in one direction but prevents it from flowing back in the opposite direction. Check valves are commonly used in plumbing systems and various industrial applications. 

The two main types of electric valves are:

Solenoid Valves: These valves use an electromagnetic coil (solenoid) to control the flow of fluids. When the coil is energised, it opens the valve, allowing the fluid to flow. When the coil is de-energised, the valve closes to stop the flow.

Motorised Valves: These valves are operated by an electric motor. The motor can turn a shaft or a disc to open or close the valve. Motorised valves are often used for precise control of fluid flow in various applications, such as heating and cooling systems.

In simple terms, the three main types of control valves are Globe Valves, Butterfly Valves, & Ball Valves.

Globe Valves: These valves have a round or globe-shaped body and are designed to regulate the flow of fluids by moving a plug or disc up and down. They are commonly used for precise control of flow rate.

Butterfly Valves: These valves have a disc that rotates on a central axis to control the flow of fluids. They are often used for on/off control and are suitable for large pipelines.

Ball Valves: Ball valves use a spherical ball with a hole in the middle to control fluid flow. They are primarily used for on/off applications and are known for their quick and reliable operation.

Actuators are used in valves to make the valves open or close automatically. Valves control the flow of liquids or gases, and actuators provide the power or force needed to move the valve into the desired position. This automation is important because it allows valves to respond to signals or commands without human intervention, making industrial processes more efficient and precise.

A directly actuated valve is a type of valve that is controlled directly by an actuator without the need for an additional external signal or power source. On the other hand, a pilot actuated valve relies on an external signal or a smaller pilot valve to control the main valve. The pilot valve receives a command, and when it opens or closes, it, in turn, controls the main valve.

Yes, in simple terms, solenoid valves have built-in actuators. The actuator in a solenoid valve is the electromagnetic coil, which, when energised, creates a magnetic field that moves a component (usually a plunger or a diaphragm) to control the flow of fluid through the valve.
