FAQs That 80% Users Interest
1. How do I decide whether the AW Double Acting / Single Acting (FC, FO) actuator suits my quarter-turn valve?
• Provides stable torque for pneumatic quarter-turn valves
• Double-acting fits high-cycle systems needing bidirectional power
• Spring-return FC/FO delivers automatic fail positioning
• Suitable for ball, butterfly, and plug valves requiring strong break torque
2. What’s the key difference between fail-close and fail-open in the AW Single Acting (FC, FO) actuator?
• Fail-close shuts the valve automatically during air loss
• Fail-open keeps flow paths open for venting or cooling lines
• Spring mechanism ensures mechanical fail-safe movement
• Choice depends on safety level, media type, and process requirements
3. What torque considerations matter when sizing an AW Double Acting pneumatic actuator?
• Supports high breakaway torque for tight-seated valves
• Requires valve torque plus a 20–30% safety factor
• Higher air pressure improves output and stroke reliability
• Prevents incomplete rotation and actuator stall when sized correctly
4. Is the AW pneumatic actuator compatible with industrial control systems?
• ISO/VDI interfaces allow direct mounting on multiple valve types
• Works with solenoid valves, limit switches, and feedback modules
• Accepts 24V DC, 110V AC, and 220V AC control input
• Integrates with PLC, SCADA, and emergency shutdown loops
