The AirTAC Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V22006A is a genuine 5/2-way solenoid valve solenoid valve with 22006A ports and an effective area of See datasheet (Cv —). It is an internally piloted spool valve that directs compressed air to double-acting cylinders and actuators.
The B03-4V22006A is AirTAC's explosion-proof build of the 4V220-06A, a 5/2-way double solenoid valve designed for hazardous or flammable atmospheres. The leading "B03-" prefix marks this as the 防爆型 version, meaning it is constructed to operate safely where standard valves could pose an ignition risk. It directs compressed air to double-acting cylinders or actuators, and its memory function holds the last pulsed position even if power is lost, with no spring to reset it.
This valve carries the 4V200 body's performance class: an effective area of 17 mm² (Cv 1.0) and a maximum frequency of 5 cycles per second. It weighs 320 g and its AC220V coil draws 4.5 VA. The 1/8" PT port suits small-bore cylinders in the 32-50 mm range. Because the exact protection level and certification for this explosion-proof build are application-specific, please confirm the rating and any zone requirements with us before installation.

Size the valve so effective area / Cv is not the bottleneck for your cylinder bore and speed. Undersized valves slow the actuator. Note 5/3 (center) versions have a smaller effective area than the 5/2 of the same body size.

Operate double-acting cylinders in environments with flammable vapors or dust, where a standard valve could be unsafe. The B03- prefix indicates an explosion-proof build, but verify the exact rating for your specific zone with us.
Use the double solenoid memory function to hold a cylinder in its last position after a control pulse, without needing continuous power. This suits fixtures or gates that must stay put during a power interruption.
Drive small clamps or pushers on assembly lines where the 1/8" port and Cv 1.0 flow are sufficient for 32-50 mm cylinders, and where the explosion-proof build adds a layer of safety in sensitive areas.
Choose the B03-4V22006A when your application runs in a potentially flammable or explosive environment and you need a double solenoid 5/2 valve with memory. The 1/8" port and Cv 1.0 flow suit 32-50 mm double-acting cylinders; step down to the 4V100 series (Cv 0.6) for smaller bores, or up to the 4V300 (Cv 1.65) for larger cylinders or faster cycling. The double solenoid design means no spring return - it holds its last position, which is ideal for applications where a momentary pulse sets the state. For replacement, match the 4V200 body, 5/2 double function, 1/8" PT port, AC220V coil, and terminal box entry. Confirm the explosion-proof rating with us to ensure it matches your zone classification.
Quick checklist
The B03- prefix marks AirTAC's explosion-proof (防爆型) build of the base 4V220-06A model. It is intended for use in potentially flammable atmospheres. The exact protection level, certification, and gas/dust group are not specified in our data - please confirm these details with us for your specific zone.
When you pulse one solenoid, the spool shifts and stays in that position even after power is removed. It holds via land friction and balanced pressure, with no spring to move it and no holding current. To change state, you pulse the opposite solenoid. This is not magnetic latching - it is purely mechanical position retention.
