What is the definition of a pneumatic actuated valve? A pneumatic actuated valve is an instrument that is used to control the flow of liquids, gases, and other materials. It consists of a valve body, an actuator, and a control system. The valve body is the part of the valve that controls the flow of the material; the actuator is the part that moves the valve body; and the control system is the mechanism that operates the actuator in order to open and close the valve. Pneumatic actuated valves are used in many industrial applications, such as in the processing of natural gas, oil, and other materials. They are also used in applications involving the regulation of pressure and temperature in a system. Pneumatic actuated valves are usually operated by air pressure, but they can also be operated by electric or hydraulic power. The advantages of these valves include their reliability, durability, and their ability to control the flow of material. They are
