AirTAC 4A230C-06 Pneumatic Valve, 4A200 Series (4A230C06)
The AirTAC AirTAC 4A230C-06 Pneumatic Valve, 4A200 Series (4A230C06) is a genuine 5/3-way 5/3 double air pilot — closed centre 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 4A200 body is published at 13.6 mm² effective area (Cv 0.8).

About the AirTAC 4A230C-06 Pneumatic Valve, 4A200 Series (4A230C06)
AirTAC's 4A230C06 is a 5/3-way double air pilot valve in the compact 4A200 body. It directs compressed air to a double-acting cylinder or actuator, and because both pilot ports are pneumatic it is thrown by an air signal from a separate signal valve - there is no coil, no wiring and nothing electrical to fail in a dusty, wet or vibrating zone. On the closed (C) centre both work ports and the exhaust are blocked, so the cylinder is held wherever it stood the moment the pilot signals stopped.
The 06 port option keeps inlet, outlet and exhaust all at 1/8 inch on PT tapered thread, which seals on the flanks and wants a wrap of PTFE tape. Flow sits at an effective area of 13.6 mm2 (Cv 0.8), the figure AirTAC publishes for the 5/3 centre of this body, with a no-load cycling rate of 3 cycles per second - ample for the ~Dia 32-50 mm cylinders this body suits. The aluminium body weighs 365 g and runs on air filtered to 40 um at 0.15-0.8 MPa.

Specifications follow the official AirTAC 4A series datasheet. AirTAC publishes the effective area / Cv published for 4A230C-08; 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 | 13.6 mm² |
|---|---|
| Flow coefficient | Cv 0.8 |
| Control signal | Compressed air (exterior pilot) |
| Pilot ports | Two pilot ports, one per side |
| Electrical parts | None — no coil, no wiring, no IP rating needed |
| Manifold base | 200M (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 4A230C-06 Pneumatic Valve, 4A200 Series (4A230C06) Is Used
Paint-booth fixture clamps
In a spray shop the 4A230C06 clamps jigs on the booth turntable with zero electrics inside the paint hazard zone. The closed centre parks the clamp rod mid-stroke when the painter's signal line goes quiet, and the Cv 0.8 flow class matches the Dia 32-50 mm bore doing the clamping.
Sawmill dust extraction gates
Woodworking dust chews up contacts and coils, so sawmills drive gate and deflector dampers pneumatically instead. The 5/3 closed centre holds a damper blade at any mid position between dumps, and the all-1/8-inch porting on this 06 model keeps tubing runs and fittings uniform and simple.
Quarry screen bed tensioners
On vibrating screen plant, where shock constantly loosens electrical terminals, this valve is pulsed by a manual or roller signal valve to reposition screen-bed tension cylinders. At 365 g it bolts straight to the machine frame, and 3 cycles per second easily covers occasional re-tensioning stops.
Is the AirTAC 4A230C-06 Pneumatic Valve, 4A200 Series (4A230C06) the Right Valve?
Size across the range both ways: the smaller 4A100 body steps down at Cv 0.6, while the larger 4A300 steps up at Cv 1.65 - the 4A200's Cv 0.8 sits between them for moderate-flow circuits. Choose the 30C closed centre when a cylinder must stop and stay put mid-stroke; pick a 5/2 (10 or 20) if you only need end-to-end travel. An air pilot beats a solenoid wherever wash-down, grain or wood dust, or heavy vibration would punish a coil, or where the valve hangs on the machine fed by one signal line from a hand, foot or roller valve. A single 4A230C06 can stand alone or bolt onto a 200M manifold base (up to 16 stations, 1/4 inch common inlet). Replacing one? Match four points exactly: body size (4A200), function (30C), port (1/8 inch) and thread (PT).
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 200M 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 A pulse is enough — the spool stays where it was last driven.
- check Fit silencers or fittings to the exhaust ports.
- check Once run on lubricated air, keep lubricating it.
AirTAC 4A230C-06 Pneumatic Valve, 4A200 Series (4A230C06) FAQ
Effective area 13.6 mm2 (Cv 0.8), max no-load frequency 3 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, weight 365 g. The air supply must be filtered to 40 um, and the valve needs no lubrication - but once it has run on lubricated air it must stay on lubricated air.
The centre blocks all five ports: both cylinder lines and the exhaust are sealed, so a double-acting cylinder stops and holds its last position. For a suspended or safety-critical load, however, add pilot-operated check valves at the cylinder ports or a mechanical brake - the spool alone is not a certified load lock.
