· Valves fitted with such actuators are sometimes called control or flow control valves in that with automatic actuation they can be integrated into control loops used for process automation. The phrase "control valve" is sometimes used to describe the valves used in hydraulic and pneumatic fluid power systems to actuate a ram, for example.
These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. Often used to extend and then retract a cylinder at different speeds, they create two actions and have two exhaust ports, which allows you to control the speed of each action by attaching a flow control valve to each exhaust port.
A flow control valve regulates the flow or pressure of a fluid. Flow Control valves normally respond to signals generated by independent devices such as flow meters or temperature gauges. Control valves are normally fitted with actuators and positioners. Pneumatically-actuated globe valves are widely used for control purposes in many industries ...

· The control valve is a controlled device that regulates the flow of a liquid or gas in a system. This regulation is accomplished by the varying resistance that the valve introduces into the system as the valve is stroked. As the valve modulates to the closed position the system pressure drop shifts to the valve and reduces the flow in the system.
Ball Valves Quarter-turn 2-way ball valves are by far the most common type of process control valve. They are 2-way (inlet and outlet), 2-position (open and closed) valves that are used for shut-off or isolation of a system, or a loop or component within a system.

Trim Set the control valve (Trim Control Valve) is the word of Plug Stem Seat Ring, which collectively set trim (trim set) itself. Positioner or position will be the key to control of the control valve. The industry standard device that converts the signal (signal standard), such as 4-20 mA, 3-15 psi as wind power to propel Actuator head movements.
Valves are used to manipulate the flow of hydraulic fluid within a hydraulic circuit and are activated either mechanically or electronically. Directional Control Valves are the most commonly used valve in a hydraulic system. Control valves direct the flow of hydraulic fluid from the pump to the actuators or other sections of the hydraulic circuit.
