Airtac 4A100 Pneumatic Control Valve 4A130EM5
The AirTAC Airtac 4A100 Pneumatic Control Valve 4A130EM5 is a genuine 5/3-way 5/3 double air pilot — exhaust centre air pilot valve with M5 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 8.6 mm² effective area (Cv 0.51).

About the Airtac 4A100 Pneumatic Control Valve 4A130EM5
The AirTAC 4A130EM5 is a 5/3-way double air pilot valve in the compact 4A100 body, sized for directing compressed air to double-acting cylinders and actuators around Dia 16-32 mm. Both positions are thrown by pilot air signals - there is no coil, no wiring and no electrical enclosure to certify. In the middle position the exhaust centre vents the A and B ports, so a connected cylinder is left free to be moved by hand, by the load, or by an external force. At centre the valve is also rated at 8.6 mm2 effective area (Cv 0.51) with a no-load maximum frequency of 3 cycle/sec, and the whole unit weighs just 165 g.
The M5 connection keeps the footprint tiny on densely packed machines, and the blank thread code makes this the PT (Rc tapered) version, which seals on the flanks and takes a wrap of PTFE tape on assembly. The sliding-column spool runs on air filtered by a 40 um element, needs no lubrication, and works from 0.15-0.8 MPa (21-114 psi) at -20 to +70 C in an aluminum-alloy body. Because nothing in the valve is electrical, it is a natural fit for paint booths, grain handling and other places where a spark source or a fragile coil would be a liability.

Specifications follow the official AirTAC 4A series datasheet. AirTAC publishes the effective area / Cv published for 4A130C-06; 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 | 8.6 mm² |
|---|---|
| Flow coefficient | Cv 0.51 |
| 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 | 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 4A100 Pneumatic Control Valve 4A130EM5 Is Used
Paint booth spray heads
Reciprocating spray nozzles in finishing booths are moved by double-acting cylinders of the Dia 16-32 mm class this valve suits. An all-air valve of Cv 0.51 carries no coil, so there is no ignition source and no wash-down corrosion near solvent-laden air.
Woodworking dust extraction gates
Gate and damper actuators on sawdust-laden extraction ducting need a valve that shrugs off conductive wood dust. The 4A100's 40 um filtered, lubrication-free spool keeps switching at up to 3 cycle/sec without electrical parts to foul.
Bottle rinser change-over slides
Wash-down bottle-rinser and filler change-over slides sit where water, caustic spray and vibration kill solenoid coils. Here the exhaust centre lets an operator slide the mechanism freely by hand during change-over, then a pilot pulse returns it to service.
Is the Airtac 4A100 Pneumatic Control Valve 4A130EM5 the Right Valve?
This is the smallest 4A body AirTAC builds, so there is no 4A body below it: if your flow needs are under this class you would move to a different product family rather than a smaller 4A. To step up, the next body is the 4A200 at Cv 1.0, roughly double the capacity of this valve. Choose this 30E exhaust-centre version when operators must be able to reposition the cylinder at rest; pick the 30C closed centre if the load must stay put, or the 30P pressure centre if both sides should stay charged.
Prefer an air pilot over a solenoid whenever the valve sits on the machine far from a control cabinet: one signal line drives it, there is no coil to burn out, wash-down and vibration cause no electrical faults, and explosive or dusty atmospheres need no coil certification. For multi-valve layouts, several 4A100 units bolt onto a 100M manifold base with a 1/4-inch common inlet, up to 16 stations. When replacing, match all four points: body size 4A100, function 30E, port M5, 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 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 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 4A100 Pneumatic Control Valve 4A130EM5 FAQ
It directs compressed air to double-acting cylinders and actuators, roughly the Dia 16-32 mm class. Published figures for this 5/3 body: effective area 8.6 mm2 (Cv 0.51), no-load maximum frequency 3 cycle/sec, operating pressure 0.15-0.8 MPa (21-114 psi), proof pressure 1.2 MPa (175 psi), temperature -20 to +70 C, and a weight of 165 g.
Both A and B work ports are exhausted at centre, so a connected cylinder floats free and can be moved by hand or by the load - useful for manual adjustment, not as a substitute for a mechanical brake on a suspended load. The valve is switched purely by compressed-air pilot signals pulsed to its two pilot ports from a separate 3/2 or 5/2 signal, hand, foot or limit valve; there is no electrical component and no wiring at all.
