The AirTAC Airtac B03-4V Explosion-Proof Solenoid Valve B03-4V41015A is a genuine 5/2-way solenoid valve solenoid valve with 41015A 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 B03-4V41015A is AirTAC's explosion-proof build of the 4V410-15A, a 5/2-way single solenoid valve engineered for double-acting cylinders and actuators in environments where flammable gases, vapors, or dust may be present. The B03- prefix signals this enhanced protective construction, making it a safer choice for hazardous process areas. With an effective area of 48 mm² and Cv of 2.82, this valve delivers the full 4V400 flow class, comfortably driving cylinders in the 80-125 mm bore range. Its spring-return design means the spool automatically resets when the AC220V coil de-energizes, requiring a constant signal to maintain the actuated position.
Weighing 590 g and rated IP65, this valve is built for demanding industrial service. The AC220V coil draws just 4.5 VA, keeping control-panel loads modest. Response time is 0.05 s or less, ensuring crisp cylinder movement. The terminal-box electrical entry simplifies wiring in permanent installations. Because this is the explosion-proof variant, you should confirm the exact protection level and certification for your specific zone with us before ordering - we'll verify it matches your site's requirements.

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 a double-acting hydraulic or pneumatic press cylinder in a solvent-handling area. The B03-4V41015A's explosion-proof build and 48 mm² effective area deliver reliable, repeatable strokes while the spring return retracts the ram on signal loss.
Pilot large process valves in a chemical facility where flammable vapors may accumulate. The 1/2" porting and Cv 2.82 provide the flow needed for fast actuation, while the B03- housing reduces ignition risk in the surrounding atmosphere.
Drive a double-acting clamping cylinder in an automotive paint booth with solvent-laden air. The AC220V coil's 4.5 VA draw keeps power consumption low, and the IP65-rated enclosure resists overspray and washdown exposure.
Choose the B03-4V41015A when you need the 4V400 body's high flow (Cv 2.82) in an explosion-proof package for a double-acting cylinder around 80-125 mm. If your cylinder is smaller, the 4V300 series (Cv 1.65) may be more economical, but for this bore range the 4V400 is the right call. As the largest 4V body, stepping up further means moving to a bigger valve series or a manifold block for multi-valve consolidation. The single-solenoid, spring-return function suits applications where a power loss must safely retract the actuator.
When replacing an existing valve, verify five points: body size (4V400), function (5/2 single), port and thread (1/2" PT), coil voltage (AC220V), and electrical entry (terminal box). The B03- prefix indicates the explosion-proof housing, so also confirm the hazardous-area rating matches your installation. If you need a different thread (G or NPT) or a grommet lead, we can supply the equivalent model.
Quick checklist
The B03- prefix identifies this as AirTAC's explosion-proof version of the standard 4V410-15A. It's built with enhanced protective construction for use in hazardous or flammable atmospheres. The performance specs - 48 mm² effective area, Cv 2.82, 590 g weight, AC220V 4.5 VA coil - are identical to the base model. However, the exact protection level and certification for your specific zone must be confirmed with us before installation.
This is a single-solenoid, spring-return 5/2 valve. When the AC220V coil is energized, the spool shifts to pressurize one port of your double-acting cylinder while exhausting the other. When power is removed, the spring pushes the spool back to its rest position, reversing the airflow. It requires a constant electrical signal to hold the actuated state - it's not a memory valve. Response time is 0.05 s or less.
