Pneumatic Fitting

AS-FS Series Speed Controller with Indicator, Elbow Type

AS-FS speed controller with indicator is a precise and efficient flow control device designed to enable the control of air flow rates, ensuring optimal performance of pneumatic cylinders and actuators. 1. Indicator window allows for numerical verification of flow rate setting, which can significantly reduce setting time and errors. 2. Body size options available in different sizes to accommodate various tubing diameters and flow requirements. 3. Control type features a larger push-lock type handle for easy operation.

Product Feature

1. The numerical indication of flow rate knob rotations reduces flow setting time and setting errors.

2. 4 indicator window directions offer improved visibility, 0°, 90°,180°, 270°.

3. Larger push-lock type knob, easy to turn large knob Easy to make fine adjustments. And marking of every 90° mark allows for easier operation.

4. Improved reproducibility of flow rate. Stable knob position when fully closed (no flow rate) onto the contact face

stopper (rotating stopper). Minimal flow rate variations between knob rotations.

5. One-touch fittings make easier to insert and remove the tube.

“Without sealant” type can be selected as a standard option.
Only polyurethane tubing is applicable for 2.
There are differences in actual rate as by the indicator window over the maximum number of rotations depending on the individual product.
The universal type is not available.
