The AirTAC Airtac 4V Solenoid Valves 4V210-08AG is a genuine 5/2-way single solenoid (spring return) solenoid valve with 08AG 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 AirTAC 4V210-08AG is a single-solenoid, 5/2-way pneumatic directional valve built on the popular 4V200 body. It directs compressed air to double-acting cylinders and actuators, energising the AC220V coil to shift the spool and returning to its home position by mechanical spring when the signal is removed. The G-thread ports provide a BSPP parallel connection, simplifying manifold mounting with a bonded seal.
With an effective area of 17.0 mm2 (Cv 1.0) and a response time of 0.05 seconds or less, this valve suits cylinder bores from approximately 32 to 50 mm. The aluminium-alloy body weighs 220 g and the AC coil draws 4.5 VA. It operates on filtered, lubricated or non-lubricated air from 0.15 to 0.8 MPa and carries an IP65 protection rating.

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 pusher that diverts cartons on a conveyor. The spring return ensures the pusher retracts safely when AC power is cut, preventing a line jam.
Directs air to a double-acting clamp cylinder on a semi-automatic assembly fixture. The 4.5 VA AC220V coil integrates directly into the facility's mains control panel.
Operates a double-acting gate or slide mechanism on processing equipment. The G1/4 parallel ports allow a clean, leak-free connection into a custom aluminium manifold block.
Choose the 4V210-08AG when you need a spring-return 5/2 valve with AC220V power and G1/4 parallel ports. For smaller cylinders below 32 mm bore, stepping down to a 4V100 series (Cv 0.6) can improve energy efficiency. If your application demands higher flow for a 63 mm or larger bore, or faster cycle rates, the 4V300 body (Cv 1.65) is a better match.
This single-solenoid configuration is ideal where the valve must default to a safe position on power loss. When replacing an existing valve, confirm all five points: 4V200 body size, single-solenoid 5/2 function, G1/4 (BSPP) thread, AC220V coil voltage, and terminal-box electrical entry. The valve can be used individually or ganged on a common sub-base manifold.
Quick checklist
With an effective area of 17.0 mm2 (Cv 1.0), it is well-matched to double-acting cylinders in the 32 to 50 mm bore range for general industrial speeds. It can drive larger bores if the cycle rate is modest, but for sustained high-speed cycling of a 63 mm or larger cylinder, a 4V300 series valve (Cv 1.65) is recommended.
The 'A' designates an AC220V coil (4.5 VA inrush), and the 'G' specifies G-thread (BSPP parallel) ports. The electrical entry is the standard terminal box. This configuration is common where the machine's control voltage is 220V AC and a parallel-thread pneumatic connection is preferred.
