AirTAC 4A110-06 Pneumatic Control Valve, 4A100 Series (4A11006)
The AirTAC AirTAC 4A110-06 Pneumatic Control Valve, 4A100 Series (4A11006) is a genuine 5/2-way single air pilot (spring return) air pilot valve with PT1/8 ports. It is a sliding-spool valve switched by a compressed-air signal instead of a coil, and it directs air to double-acting cylinders and actuators. The 4A100 body is published at 10.2 mm² effective area (Cv 0.6).

About the AirTAC 4A110-06 Pneumatic Control Valve, 4A100 Series (4A11006)
The AirTAC 4A11006 is a 5/2-way air pilot valve that directs compressed air to double-acting cylinders and actuators. There is no coil inside it: a pilot signal applied to the control port throws the spool, and a built-in spring pushes it straight back the moment that signal is released, so the valve follows its signal valve instead of remembering a position. This SKU has 1/8in ports cut with PT (Rc tapered) thread, which seals on the flanks of the joint and takes a wrap of PTFE tape rather than a face washer.
Flow capacity is an effective area of 10.2 mm2 (Cv 0.6) with a no-load cycling rate of up to 5 cycles per second - a class that suits double-acting cylinders around Dia 16 to 32 mm. The sliding-column spool sits in a compact aluminum-alloy body weighing only 85 g, runs on 0.15-0.8 MPa (21-114 psi) air, and needs a 40 um filtration element upstream. Lubrication is not required, but once the valve has run on lubricated air it must stay lubricated.
AirTAC 4A110-06 Pneumatic Control Valve, 4A100 Series (4A11006) Technical Specifications

| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 0.8 MPa (21 – 114 psi) |
| Proof pressure | 1.2 MPa (175 psi) |

Specifications follow the official AirTAC 4A series datasheet. AirTAC publishes the effective area / Cv published for the 1/8" port; other port and centre options of this body share the same casting but are not separately rated. Max frequency is the no-load figure. Confirm the thread standard (PT / G / NPT) against the product label before piping.
Flow & Piloting
| Effective area | 10.2 mm² |
|---|---|
| Flow coefficient | Cv 0.6 |
| Control signal | Compressed air (exterior pilot) |
| Pilot ports | One pilot port; spring returns the spool |
| Electrical parts | None — no coil, no wiring, no IP rating needed |
| Manifold base | 100M (up to 16 stations) |
Because there is nothing electrical in the valve, the 4A suits wash-down, explosive-atmosphere and high-vibration areas where a solenoid would need certification. Size the valve so effective area / Cv is not the bottleneck for your bore and speed; the 5/3 centre versions have a smaller effective area than the 5/2 of the same body.

Where the AirTAC 4A110-06 Pneumatic Control Valve, 4A100 Series (4A11006) Is Used
Paint booth gun carriages
A spray-booth reciprocator carrying double-acting cylinders around Dia 16-32 mm falls squarely inside this valve's Cv 0.6 class, and with no coil in the booth the 4A11006 poses no ignition-component concern in solvent vapour zones.
Woodshop blast gates
Dust-extraction diverter gates on a planer or saw line cycle a small double-acting ram a few times a minute - well within the 5 cycle/sec no-load rating - and the 85 g valve bolts straight onto the duct frame, switched by a hand lever valve at the operator station.
Quarry plant tailgate rams
On tipping bodies and chute closers the valve sits on the chassis where vibration and grit kill electronics; the air pilot needs only a single signal line from a cab-mounted valve, and 40 um filtered air at 0.15-0.8 MPa keeps the 10.2 mm2 spool moving.
Is the AirTAC 4A110-06 Pneumatic Control Valve, 4A100 Series (4A11006) the Right Valve?
This is the smallest body in the 4A range, so there is no smaller 4A to step down to - below this flow class you would move to a different AirTAC product family entirely. For more air, step up to the 4A200 body at Cv 1.0. Pick the double-pilot 4A120 if you want pulse-held memory instead of a spring return, or a 4A130C/E/P if the centre state must hold, exhaust or pressurise the cylinder. Replacing a worn unit means matching all four code points: 4A100 body, function 10, 1/8in port, PT thread. Where a solenoid coil is a liability - wash-down bays, dust-laden shops, hazardous atmospheres or a valve bolted to the machine far from any control cabinet - the air pilot is the natural choice, and a 100M manifold base lets up to sixteen valves share one 1/4in common inlet.
Quick checklist
- ✓ Required flow (Cv) for cylinder & speed
- ✓ Function: single / double / 5-3 centre
- ✓ Pilot air available at 0.15 MPa or above
- ✓ Port thread (M5 / 1/8 / 1/4 / 3/8 / 1/2)
- ✓ Single valve or 100M manifold base?
Installation & Piloting Notes
- check Use clean air filtered to 40µm or finer.
- check Keep the main line within 0.15 – 0.8 MPa.
- check Drive the pilot port from a 3/2 or 5/2 signal valve.
- check Hold the pilot signal on; releasing it springs the spool back.
- check Fit silencers or fittings to the exhaust ports.
- check Once run on lubricated air, keep lubricating it.
AirTAC 4A110-06 Pneumatic Control Valve, 4A100 Series (4A11006) FAQ
It is a 5/2-way valve sized for double-acting cylinders roughly Dia 16-32 mm. The published figure set: effective area 10.2 mm2 (Cv 0.6), maximum no-load frequency 5 cycles per second, operating pressure 0.15-0.8 MPa (21-114 psi), proof pressure 1.2 MPa (175 psi), temperature -20 to +70 C, with air filtered by a 40 um element and lubrication not required.
Because this is a single-pilot spring-return valve, the pilot signal must be held for the spool to stay thrown; the moment the signal is dropped, the spring returns the spool and the cylinder vents and re-pressurises to its rest state. The pilot is fed from the same compressed-air supply through a 3/2 or 5/2 signal valve, a hand or foot valve, or a roller limit valve - there are no electrical parts anywhere in the valve.
