Airtac PSL Throttle Speed Control Fitting PSL10-02A
The AirTAC Airtac PSL Throttle Speed Control Fitting PSL10-02A is a genuine speed controller, threaded elbow with knob with aluminium-alloy locking cap and fixed tube direction, used to set the speed of a pneumatic cylinder by throttling its air.

About the Airtac PSL Throttle Speed Control Fitting PSL10-02A
The PSL10-02A is an inline speed controller for Dia 10 mm soft nylon or polyurethane tubing on a 1/4 in PT thread. Its A suffix means meter-out: flow entering from the thread port and leaving through the tube is throttled by the brass needle, while the return direction passes freely. In practice that means you throttle the exhaust of the actuator, and the trapped back-pressure acts as a cushion so the stroke stays smooth. AirTAC treats meter-out as the first-priority control method, especially where a solenoid valve drives a double-acting cylinder, because meter-in throttling on that same cylinder tends to stick-slip as the load changes.
Adjustment is a knob with an aluminium locking cap: set the speed by hand, then screw the cap down so machine vibration cannot drift the setting between shifts. The brass body screws directly into the cylinder or valve port, and the tube outlet points in a fixed direction, so decide the port orientation at design time - the swivelling alternative at this size is the PSS range. The throttling column and body are brass, the holder and body sections are PBT, seals are NBR, and the standard finish is grey with a D suffix ordering black.

POM release button and chuck, aluminium-alloy guide, stainless spring gasket, NBR O-ring; body brass or PBT depending on the part. A speed controller is not a shut-off valve - a small leak past a fully closed needle is normal. Close it before applying air, and turn it open slowly. AirTAC publishes flow as a characteristic curve rather than a single figure, so no L/min value is listed.

Meter-Out or Meter-In?
- check Meter-out (A) is the default. It throttles the air LEAVING the cylinder, so the piston runs against a back-pressure cushion and moves smoothly.
- check Use meter-out on double-acting cylinders - it is the one AirTAC lists as first priority.
- check Meter-in (B) throttles air ENTERING the cylinder. It suits single-acting cylinders and air motors.
- check Meter-in on a double-acting cylinder tends to give a jerky, stick-slip stroke under varying load.
- check Fit the controller at the cylinder port, not at the valve, so the throttled volume is as small as possible.
Where the Airtac PSL Throttle Speed Control Fitting PSL10-02A Is Used
SMT pick-and-place Z-stroke
Damping the descent of a placement head on a chip-shooter gantry, so fine-pitch components are set onto the solder paste instead of being slammed onto the pad.
Clamp closing on finished panels
Metering a clamp cylinder as it closes on lacquered oak tabletop panels in a furniture line, letting the pad touch the finished face gently and leave no pressure mark.
Carton indexing pusher
Timing a pusher that diverts cartons off a packaging conveyor at the correct chain pitch, with meter-out control keeping the stroke repeatable cycle after cycle.
Is the Airtac PSL Throttle Speed Control Fitting PSL10-02A the Right Part?
Dia 10 is the top of the PSL ladder on the 1/4 in thread (Dia 6, 8 and 10 exist on this thread), so there is no larger bore on 1/4 in; to step up in bore you move to the 3/8 in thread, which adds Dia 12. If your cylinder ports or air demand are smaller, the Dia 8 / 1/4 in version below is the usual choice, giving a lighter fitting with the same thread. Whichever bore you pick, mount the controller at the cylinder port rather than at the valve, so only the short hose between fitting and actuator sits inside the throttled circuit and the speed response stays crisp.
If you prefer an adjustment that cannot be knocked out of position by hands or hose whip, the push-lock cap equivalent is the PTL range, which carries the same tube and thread options at 1/4 in (Dia 6, 8 and 10). For a port where the fitting must swivel to line up with the hose run, choose the PSS universal body instead of the fixed-outlet PSL.
Quick checklist
- ✓ Tube outside diameter matches exactly
- ✓ Thread size and standard match the port
- ✓ Working pressure within 0 - 1.0 MPa (0 - 10 kgf/cm2)
- ✓ Temperature within -20 to +70 °C
- ✓ Meter-out (A) unless you know you need meter-in
Airtac PSL Throttle Speed Control Fitting PSL10-02A FAQ
Working pressure 0-1.0 MPa (0-10 kgf/cm2), negative pressure -750 mmHg (10 Torr) and proof pressure 1.5 MPa, usable from -20 to +70 C. This SKU is the Dia 10 mm tube size on a 1/4 in PT thread, meter-out (A) control, grey as standard with a D suffix ordering black.
No. Like every speed controller in this family it is built to throttle, and even fully closed it still passes a slight leak by design, so it must not be relied on to isolate a circuit. For positive isolation use the PHV finger valve, a manual quarter-turn shut-off. Note also that no silencer is built into this part; if exhaust noise at the valve matters, fit a silencer as a separate item.
