About the AirTAC 4V210-06BI Solenoid Valve, 5/2-way, PT1/8, DC24V, grommet entry (4V21006BI)
The 4V210-06BI is a 5/2-way single-solenoid directional control valve that directs compressed air to double-acting cylinders and actuators. It requires a constant DC24V signal to hold the actuated position; de-energising the coil immediately springs the spool back to its home state, making it a safe default for applications where the cylinder must retract on power loss.
This model arrives pre-wired with a 0.5 m flying lead via a DIN-style grommet entry, eliminating the need to open a terminal box during installation. The 3.0 W DC coil keeps heat low, and the sliding-column spool achieves a response time of 0.05 s or less. With an effective area of 17.0 mm² (Cv 1.0) and a 1/8 in PT port, it suits double-acting cylinders in the ~O32-50 mm range.

Flow & Coil Options
| Effective area | 17.0 mm² |
|---|---|
| Flow coefficient | Cv 1.0 |
| Response time | ≤ 0.05 s |
| Coil power | AC 4.5 VA · DC24V 3.0 W · DC12V 2.5 W |

Where the AirTAC 4V210-06BI Solenoid Valve, 5/2-way, PT1/8, DC24V, grommet entry (4V21006BI) Is Used
Small-Bore Cylinder Actuation
Drives double-acting cylinders on diverters and stops in compact packaging conveyors, where the 1/8 in port and Cv 1.0 flow match the speed requirements of O32-50 mm actuators.
Pick-and-Place End Effectors
Controls gripper open/close actions on lightweight assembly robots. The spring-return function ensures the gripper releases the part if the DC24V signal is interrupted.
Pre-Wired Machine Sub-Assemblies
The grommet-style flying lead integrates cleanly into cable carriers on moving slides, avoiding a bulky terminal box and speeding up OEM panel wiring.
Is the AirTAC 4V210-06BI Solenoid Valve, 5/2-way, PT1/8, DC24V, grommet entry (4V21006BI) the Right Valve?
Choose this 4V210-06BI when you need a compact 1/8 in valve with a pre-wired DC24V grommet connection and the spring-return safety behaviour. If your cylinder is smaller (O20 or below), stepping down to the 4V100 series (Cv 0.6) can improve energy efficiency. For larger bores or faster cycle times above 5 cycles per second, moving up to the 4V300 body (Cv 1.65) provides the extra flow.
When replacing an existing valve, match five points: confirm the body is 4V200 size, the function is 5/2 single solenoid (spring return), the port is 1/8 in PT thread, the coil voltage is DC24V, and the electrical entry is a grommet lead-out. If you are building a multi-station manifold, verify the base shares the same 4V200 pitch.
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 4V210-06BI Solenoid Valve, 5/2-way, PT1/8, DC24V, grommet entry (4V21006BI) FAQ
With an effective area of 17.0 mm² (Cv 1.0), it provides sufficient flow for double-acting cylinders approximately O32 to O50 mm in bore. For smaller O20 mm cylinders, a 4V100 series valve (Cv 0.6) may offer finer control.
Yes. The 4V210-06BI is a single-solenoid, spring-return valve. The DC24V coil must remain energised to hold the spool in the actuated position. When power is removed, the internal spring forces the spool back to its normal state.
