Control Valves
Control valves are mechanical devices used in industrial systems to regulate the flow, pressure, temperature, or level of fluids (liquids, gases, or steam) by opening, closing, or partially obstructing a passage.
👉 In simple terms:A control valve is like a “smart tap” that automatically adjusts flow based on system needs.
⚙️ How a control valve works
A control valve typically works as part of an automatic control loop:
A sensor measures a process variable (flow, pressure, temperature)
A controller compares it with the desired setpoint
The controller sends a signal to the valve actuator
The actuator moves the valve stem
The valve opens or closes to adjust flow
