Airtac 4A100 Pneumatic Control Valve 4A130PM5
The AirTAC Airtac 4A100 Pneumatic Control Valve 4A130PM5 is a genuine 5/3-way 5/3 double air pilot — pressure 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 4A130PM5
The AirTAC 4A130PM5 is the pressure-centre version of the smallest 4A air pilot valve. It directs compressed air to a double-acting cylinder or actuator, and at the centre position both working ports A and B stay connected to supply pressure, so each side of the actuator remains live instead of being blocked or vented. The spool is thrown by a pulsed air signal applied to one of the two pilot ports - there is no coil anywhere in the valve, so nothing electrical has to be certified, sealed or shielded.
This M5-port body publishes an effective area of 8.6 mm2 (Cv 0.51) and a no-load maximum of 3 cycles per second, and at 165 g it is light enough to mount directly on small machines and fixtures. It runs on any clean, dry air filtered to 40 um over 0.15-0.8 MPa (21-114 psi), tolerates -20 to +70 C, needs no lubrication, and can bolt onto a 100M manifold base alongside other 4A100 valves.

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 4A130PM5 Is Used
Mini gripper on an electronics assembly bench
A compact parallel gripper swapping small PCBs or connectors sits well inside the 8.6 mm2 (Cv 0.51) flow class, and the pressure centre keeps both gripper chambers fed so the jaws are not left vented between pick-and-place strokes.
Small air damper in a paint mixing room
A paint shop's flammable-atmosphere rules make coils unwelcome, so a hand signal valve throws this pilot valve to stroke a Dia 16-32 mm damper cylinder, with both sides pressurised at centre to help the blade hold its set position.
Bench-top test rig clamping fixture
A lab fixture that clamps test coupons between cycles uses the 30P centre to keep both sides of a small double-acting clamp cylinder live, and the 165 g valve bolts straight to the frame or a 100M manifold.
Is the Airtac 4A100 Pneumatic Control Valve 4A130PM5 the Right Valve?
Pick the 30P function when you want the actuator's both chambers pressurised at rest - handy where a little back-pressure on each side helps resist drift, and unlike the 30E exhaust centre the cylinder never vents at centre. If you need the cylinder positively blocked instead, choose the 30C closed-centre code; if you want it free to float, choose 30E. If you do not need a centre condition at all, a 5/2 valve in this body gives you 10.2 mm2 (Cv 0.6) and 5 cycles per second. The 4A100 is the smallest 4A body there is - there is no smaller 4A to step down to, so for lighter duties you would leave the 4A family; for more flow, step up to the 4A200 at Cv 1.0. An air pilot beats a solenoid wherever electrics are a liability: no coil to burn out, no ignition source in dusty or flammable air, and one signal line reaches the valve from far away.
For a like-for-like replacement, match all four code segments: 4A100 body, function 30P, port M5, and the thread letter (blank here for the standard PT designation). Single valve or a 16-station 100M bank - both work.
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 4A130PM5 FAQ
It is a 5/3 pressure-centre valve for double-acting cylinders and actuators of roughly Dia 16-32 mm. Published figures for this body: effective area 8.6 mm2 (Cv 0.51), no-load maximum frequency 3 cycles per second, operating pressure 0.15-0.8 MPa (21-114 psi) with a 1.2 MPa (175 psi) proof pressure, air filtered to 40 um, and 165 g weight. It switches between centre and end positions only on an air signal - both working ports remain connected to supply at centre.
A short pulse of compressed air at one pilot port pushes the spool across; a pulse at the other port pushes it back. The spool is held at its last position by land friction and balanced pressures - no spring, no detent, no magnet - so it keeps its position even if pilot air is lost. Between pulses you need no signal at all, and because there is nothing electrical in the valve it can sit on the machine, far from any control cabinet, fed by a single air line.
