Overview
The SMC AS2201F is a compact pneumatic meter-out flow control valve from SMC’s One-Touch AS Series. Designed as a speed controller, this valve provides precise regulation of compressed air flow rates in automation systems. The AS2201F combines reliable needle-valve metering with convenient push-lock connection options, making it suitable for OEM integration and field service applications where fast maintenance and flexible piping are required.
Key Features
- One-Touch Push-Lock Connectors: Available outlet sizes from 1/8″ to 6mm OD, simplifying quick disconnect and reconnect for service
- Meter-Out Control: Smooth load-holding and speed control capability for pneumatic cylinders and actuators
- Elbow Piping Type: Compact 90° elbow configuration saves space in tight panel layouts
- Adjustable Needle Valve: Fine-tuning screw delivers precise flow regulation and repeatability
- Multiple Port Configurations: Versions with R 1/8″, R 1/4″ (male) inlet threads and variable outlet connectors
- RoHS Compliant: Meets environmental standards for industrial automation use
