Process control valves are essential devices used in industrial automation to regulate the flow, pressure, temperature, or level of fluids within a system. These valves respond to signals from controllers and adjust the process variables accordingly to maintain desired setpoints, ensuring efficiency, safety, and product quality.
Process control valves are actuated valves that automatically modulate fluid flow based on signals from a control system. These valves play a vital role in maintaining consistent operation within industrial processes such as chemical manufacturing, water treatment, oil and gas refining, and food processing.
Used for precise flow control.
Provide good throttling capabilities.
Offer quick shutoff and reliable flow control.
Ideal for on/off control with low-pressure drops.
Lightweight, cost-effective, and suitable for large flows.
Used in systems requiring moderate control.
Excellent for sanitary and corrosive applications.
Common in pharmaceutical and food industries.
Comes with pneumatic, electric, or hydraulic actuators.
Adjusts valve position based on controller input.
| Component | Function |
|---|---|
| Valve Body | Main structure that houses internal parts. |
| Actuator | Moves the valve stem to open or close the valve. |
| Positioner | Ensures the valve reaches the exact desired position. |
| Controller Input | Sends signals (typically 4-20 mA) to control the valve. |
Chemical Processing: Controls reaction conditions.
Water Treatment: Maintains pressure and flow in pipelines.
HVAC Systems: Regulates temperature and airflow.
Pharmaceutical Production: Ensures precise dosing and fluid management.
