About the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V22008B
The B03-4V22008B is AirTAC's explosion-proof build of the 4V220-08B, a 5/2-way double solenoid valve with memory function. It directs compressed air to double-acting cylinders and actuators, holding its last pulsed position without power. The B03 prefix marks this as the explosion-proof version, intended for hazardous or flammable atmospheres - confirm the exact protection rating and certification for your zone with us.
With an effective area of 17 mm² (Cv 1.0) and a 320 g body, this valve suits cylinders in the 32-50 mm range. The DC24V coil draws 3.0 W, and response time is 0.05 s or less. The IP65-rated enclosure and terminal box entry make it a robust choice for demanding industrial environments.

Specifications follow the official AirTAC 4V series datasheet. Lubrication not required. Confirm coil voltage and thread (PT / NPT / G) against the product label before wiring.
Flow & Coil Options
| Effective area | See datasheet |
|---|---|
| Flow coefficient | Cv — |
| Response time | ≤ 0.05 s |
| Coil power | AC 3.5–4.5 VA · DC 2.5–3.0 W |
| Protection / insulation | IP65 (DIN40050), B-class |
| Voltage options | DC24V, DC12V, AC110V, AC220V |

Where the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V22008B Is Used
Automated Assembly Stations
Memory-hold actuation for clamping and positioning fixtures in assembly lines, where maintaining cylinder state during brief power interruptions improves workflow continuity.
Packaging Machinery
Controls double-acting pushers and guides in carton erectors and case packers, leveraging the 17 mm² effective area for reliable mid-cycle operation.
Material Handling
Operates transfer arms and stop gates on conveyors in facilities with flammable dust or vapor risks, where the explosion-proof build is specified.
Is the Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V22008B the Right Valve?
Choose the B03-4V22008B when you need a double solenoid 5/2 valve with memory hold in a potentially explosive atmosphere. The memory function means it retains its last position on power loss, unlike a spring-return valve. For smaller cylinders below 32 mm, consider the 4V100 series (Cv 0.6); for larger bores or faster cycles, step up to the 4V300 (Cv 1.65).
When replacing an existing valve, match the 4V200 body size, the 5/2 double solenoid function, the PT1/4 ports, the DC24V coil, and the terminal box entry. The B03 prefix specifically indicates the explosion-proof variant - verify the protection level with us before installation.
Quick checklist
- ✓ Required flow (Cv) for cylinder & speed
- ✓ Function: single / double / 5-3 center
- ✓ Coil voltage (DC24 / AC220 …)
- ✓ Port thread (M5 / 1/8 / 1/4 / 3/8 / 1/2)
- ✓ Single valve or manifold base?
Installation & Wiring Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 0.8 MPa operating pressure.
- check Match coil voltage to your controller output.
- check Use the manual override to test before powering.
- check Fit silencers or fittings to the exhaust ports.
- check Wiring by qualified personnel per AirTAC docs.
Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V22008B FAQ
B03- is AirTAC's designation for the explosion-proof version of the base 4V220-08B model. It is built for use in hazardous or flammable atmospheres. The exact protection level, certification body, and gas/dust group are not listed here - you must confirm these details with us for your specific zone.
The spool stays in the position it was last pulsed to, held by land friction and balanced pressure. There is no spring to return it and no holding current required. This is not magnetic latching - the valve simply maintains its state without power.
