Control Valve Functionality: A control valve regulates fluid flow within a process system by using a positionner and an actuator, allowing for precise control based on an external control signal. Key Components: 1. Control Valve: The valve itself, which can be a globe, ball, or butterfly valve, that adjusts fluid flow based on its opening position. 2. Actuator: Converts the control signal into mechanical movement to set the valve’s position. * Pneumatic Actuator: Uses compressed air to move a di

*Types of Valves* - *1. Gate Valve*: - *Function*: On/off control, minimal flow restriction. - *Use*: Isolation, frequent operation. - *2. Globe Valve*: - *Function*: Regulating flow, precise control. - *Use*: Throttling, controlling flow rate. - *3. Ball Valve*: - *Function*: On/off control, quarter-turn operation. - *Use*: Quick shut-off, frequent operation. - *4. Butterfly Valve*: - *Function*: Regulating flow, low pressure drop. - *Use*: Large pipe sizes, low-pressure applications. - *5. Che
