What is a pneumatic valve? How about an actuator?
In the first context, a pneumatic valve is a device that is used to control or modulate the flow of air (or another inert gas) in a pneumatic system. They do so by controlling the air or gas at the source, regulating its passage as needed into tubing, pipes, or devices in an automated pneumatic system.
A valve actuator is a tool that controls the opening and closing of valves. Now it is often used in many industries from oil and gas to mining.
