The AirTAC Airtac 4V Solenoid Valves 4V210-08CG is a genuine 5/2-way single solenoid (spring return) solenoid valve with 08CG 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.
The 4V210-08CG directs compressed air to double-acting cylinders and actuators, using a single-solenoid, spring-return mechanism. Energise the AC110V coil to shift the spool and extend the cylinder; de-energise it and the internal spring snaps the spool back, retracting the actuator. This configuration ships with a DIN-style grommet entry and a 0.5 m pre-wired flying lead, making electrical hook-up quick on the machine.
Built on the 4V200 body, it delivers a 17.0 mm² effective area (Cv 1.0) and a response time of 0.05 s or less, suiting it for ~O32-50 mm bore cylinders. The G (BSPP) parallel threads on the 1/4-inch ports provide a clean, O-ring sealed connection that simplifies plumbing on aluminium manifolds and sub-bases.

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.

Controls a double-acting pneumatic ram that pushes cartons onto a conveyor. The spring-return action ensures the pusher retracts on power loss, preventing a jam.
Drives a clamping cylinder on a semi-automatic assembly jig. The AC110V grommet wiring and BSPP ports simplify installation on European-style aluminium profile frames.
A dependable pilot valve for medium-bore actuators in pick-and-place units. The 17.0 mm² effective area provides a balanced flow for smooth, controlled motion.
Choose the 4V210-08CG when your circuit needs a single-solenoid 5/2 valve with an AC110V supply and you prefer the convenience of a grommet lead-out with BSPP ports. The 4V200 body sits in the middle of the AirTAC range—step down to a 4V100 (Cv 0.6) for compact O20 mm cylinders, or move up to a 4V300 (Cv 1.65) when driving O63 mm bores or needing faster fill times. For a double-solenoid version that holds position without constant power, look at the 4V220 series.
When replacing an existing valve, match five points: body size (4V200), function (single 5/2), port and thread (1/4-inch G/BSPP), coil voltage (AC110V), and electrical entry (grommet). If you are building a multi-station manifold, confirm the base is machined for G-thread fittings and order the correct sub-base plate.
Quick checklist
With a Cv of 1.0 and a 17.0 mm² effective area, it suits double-acting cylinders in the ~O32 to O50 mm range. It can drive smaller or larger bores, but cycle speed will vary—use a 4V100 for O20 mm cylinders or a 4V300 for O63 mm and above for optimal efficiency.
Yes. The single-solenoid design requires constant power on the AC110V coil to hold the shifted position. When the signal is removed, the mechanical spring returns the spool to its home position, exhausting the cylinder's previously pressurised port.
