Control Valve  

A control valve is a type of valve that is employed to control fluid flow (gases or liquids) by adjusting the passage area of the flow. It adjusts to the signals provided by a control system to provide desired flow rates, pressures, levels, or temperatures in a process system.  

Key Parts of Control Valve 

• Valve Body – The principal casing containing internal parts and controlling fluid flow. 
• Actuator – Translates the control signal into motion in mechanical form to open or shut off the valve. 
• Valve Plug or Disc – Moves inside the valve body in order to modulate the flow. 
• Stem – Links the actuator to the plug and conveys motion. 
• Positioner – Maintains the valve at the precise desired position depending on the control signal. 

Working Mechanism 

Control valves function on the basis of a command from a process controller. The controller provides a signal (usually pneumatic or electrical) to the actuator. The actuator moves the valve plug and stem, varying the rate of flow through the valve. The positioner corrects for accuracy by coordinating the valve position and control signal for the best process conditions.
