Open- and closed-loop control of fluid flows
Products in chemical plants must meet extremely high requirements:
- Sturdy design
- Appropriate materials
- Explosion-proof designs
- Sealing
- Ease of cleaning
- Pressure and vacuum resistance
- Temperature resistance
- Resistance to extreme temperature
- Weather resistance
- Reliability
Automation solutions from Festo:
- Air preparation for use in explosive and non-explosive areas
- Solenoid valves with explosion-proof coils mounted directly on the actuator (NAMUR interface) in explosive areas
- Solenoid valves in explosion-proof cabinets with tubing to the actuators
- Solenoid valves in a control cabinet outside the explosive area with tubing to the drives
- Intrinsically safe valve terminals in a control cabinet inside the explosive area for activating groups of actuators
- Valve terminals outside the explosive area for activating groups of actuators
- I/O remote systems outside the explosive area for recording and outputting electrical signals
- Quarter-turn and linear actuators with and without sensor boxes outside the explosive area for opening/closing process valves
- Quarter-turn and linear actuators with and without sensor boxes inside the explosive area for opening/closing process valves
Use of single-acting actuators for the safety setting of the valves and fittings (e.g. "normally closed") if the power supply fails
