AirTAC 4V210-08 Solenoid Valve, 4V200 Series (4V21008H-AM)
The AirTAC AirTAC 4V210-08 Solenoid Valve, 4V200 Series (4V21008H-AM) is a genuine 5/2-way single solenoid (spring return) solenoid valve with AM ports and an effective area of 17.0 mm² (Cv 1.0). It is an internally piloted spool valve that directs compressed air to double-acting cylinders and actuators.

About the AirTAC 4V210-08 Solenoid Valve, 4V200 Series (4V21008H-AM)
This 4V210-08H-AM belongs to AirTAC's mid-size 4V200 family: a single-solenoid 5/2 spool valve with 1/4in PT working ports and a conventional terminal-box connection. Its spring-return logic is simple - coil energised, the cylinder advances; coil de-energised, the internal spring returns the spool and the rod retracts without needing any second electrical command.
Flow sits at Cv 1.0 (17.0 mm2 effective area), enough for double-acting cylinders in the O32-50 mm range running up to 5 cycles/s with a 0.05 s worst-case response and a 220 g aluminium body. Because the -H-AM build is a factory variant, confirm the exact coil voltage with us before ordering - the 4V200 platform is otherwise stocked with AC220V, AC110V, AC24V, DC24V and DC12V coils.

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 | 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 |
| Protection / insulation | IP65 (DIN40050), B-class |
| Voltage options | DC24V, DC12V, AC110V, AC220V |
| Manual override | Yes (locking / non-locking) |
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.

Where the AirTAC 4V210-08 Solenoid Valve, 4V200 Series (4V21008H-AM) Is Used
Machined-part ejector pushers
A short-stroke pusher knocking finished aluminium housings off a CNC fixture can cycle this 5/2 spool up to 5 times a second; Cv 1.0 keeps an O50 ejector, good for 98 kgf at 0.5 MPa, moving without lag.
Carton diverter gates
Deflecting boxes along a packing line, the valve's 0.05 s switching and 1/4in PT ports let a double-acting diverter cylinder reverse quickly enough to keep pace with conveyor throughput.
Weld-fixture locating pins
Lift-and-locate pins in an automotive body shop extend and retract on held coil signals; because the spring return is purely mechanical, the pins withdraw automatically whenever control power fails.
Is the AirTAC 4V210-08 Solenoid Valve, 4V200 Series (4V21008H-AM) the Right Valve?
Both directions matter when sizing: an O40 double-acting cylinder delivering about 63 kgf at 0.5 MPa sits squarely inside this valve's Cv 1.0 class; an O32 bore that rarely cycles can drop to the 4V100 (Cv 0.6), while a hard-worked O50 bore, or anything wanting a faster stroke, belongs on the 4V300 (Cv 1.65). Pick the double-solenoid 4V220 instead if the rod must stay put after a power cut, or a 4V230 centre type for mid-stroke stop, exhaust or pressure behaviour.
For a like-for-like replacement, lock in five parameters: 4V200 body, function 10, port 08 in PT thread, the coil voltage printed on your old nameplate, and terminal-box versus grommet entry.
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 4V210-08 Solenoid Valve, 4V200 Series (4V21008H-AM) FAQ
Flow class: 17.0 mm2 effective area, Cv 1.0, up to 5 cycles per second, response within 0.05 s. Pressure: 0.15-0.8 MPa working, 1.2 MPa proof, air filtered by a 40 um element, usable from -20 to +70 C. Build: aluminium body at 220 g, IP65 (DIN40050), class B insulation, manual override, terminal-box entry, and 1/4in PT inlet and outlet with a 1/8in PT exhaust.
The 4V210-08 base valve is stocked with AC220V, AC110V, AC24V, DC24V or DC12V coils (4.5 VA down to 2.5 W); -H-AM designates a factory build variant, so state your supply voltage at RFQ and we will confirm or quote the exact coil. Everything else - spring-return 5/2 function, 1/4in PT ports, terminal-box entry and IP65 sealing - matches the standard 4V210-08.
