About the AirTAC 4V410-15BI Solenoid Valve, 5/2-way, PT1/2, DC24V, grommet entry (4V41015BI)
The 4V410-15BI is a single-solenoid, spring-return 5/2-way pneumatic directional valve built on the largest 4V body size. It directs compressed air to one side of a double-acting cylinder while exhausting the other, and the internal spring forces the spool back to its home position the moment the DC24V signal is removed—making it ideal for applications where a fail-safe default position is required on power loss.
This specific configuration arrives with a grommet-style electrical entry, meaning a 0.5 m flying lead is pre-wired into the IP65 enclosure so you can connect it directly without a terminal box. The valve’s 48.0 mm² effective area (Cv 2.82) and sub-0.05 s response time suit large-bore cylinders in the ~O80–125 mm range, and the DC coil draws just 3.0 W.

Where the AirTAC 4V410-15BI Solenoid Valve, 5/2-way, PT1/2, DC24V, grommet entry (4V41015BI) Is Used
Large-Bore Cylinder Actuation
Drives double-acting cylinders up to ~125 mm bore on packaging and palletising conveyors, where the spring-return action guarantees the actuator retracts to a safe position when the DC24V signal drops.
Heavy Clamping & Fixturing
Controls pneumatic clamps on machining centres and welding jigs. The 3.0 W DC coil runs cool in continuous-duty holds, and the grommet lead simplifies wiring inside crowded control cabinets.
Press & Forming Assist
Pilots large air-operated presses and forming tools. With a Cv of 2.82 and a 3 cycles/sec maximum frequency, it delivers the rapid fill and exhaust needed for consistent cycle times on big-bore tooling.
Is the AirTAC 4V410-15BI Solenoid Valve, 5/2-way, PT1/2, DC24V, grommet entry (4V41015BI) the Right Valve?
Choose the 4V410-15BI when you need a single-coil 5/2 valve with a pre-wired DC24V connection. If your cylinder is smaller—roughly O32–63 mm—the 4V300 series (Cv 1.65) is often a better match and saves air. For cylinders above O125 mm, the 4V400 is the largest 4V body, so you would step up to a larger valve series or manifold multiple units.
When replacing an existing valve, match five points: body size (4V400), function (single-solenoid 5/2), port and thread (1/2 in PT), coil voltage (DC24V), and electrical entry (grommet with flying lead). The spring-return design is right for circuits that must default to a known position when the machine stops or E-stops.
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 4V410-15BI Solenoid Valve, 5/2-way, PT1/2, DC24V, grommet entry (4V41015BI) FAQ
With an effective area of 48.0 mm² (Cv 2.82), it is typically paired with double-acting cylinders in the ~O80–125 mm bore range. Actual speed depends on operating pressure, tubing diameter and length, and the load, so size the valve using its Cv against your cylinder’s swept volume and target cycle rate.
No—the IP65 rating is maintained. The grommet (DIN-style) provides a sealed lead-out with a 0.5 m flying wire, so you get the same dust-tight, water-jet-resistant protection as the terminal-box version, just with a faster plug-and-wire installation.
