The AirTAC Airtac 4V Solenoid Valves 4V32010AG is a genuine 5/2-way double solenoid (memory) solenoid valve with 32010AG ports and an effective area of 28.0 mm² (Cv 1.65). It is an internally piloted spool valve that directs compressed air to double-acting cylinders and actuators.
The AirTAC 4V320-10AG is a 5/2-way double solenoid valve that directs compressed air to double-acting cylinders and actuators through 3/8in ports cut in G (BSPP parallel) thread. This build carries the AC220V coil at 4.5 VA, wired out through a terminal box. Because both positions are solenoid-driven, the spool behaves as a memory: it stays where it was last pulsed, held by land friction and balanced pressure, with no spring to move it and no holding current drawn - it is not a magnetically latched design. Flow sits in the mid-large AirTAC class at 28.0 mm2 effective area (Cv 1.65), enough to fill ~O50-80 mm double-acting bores on machines that need a valve to remember its state. The spool reacts in 0.05 s or less and cycles up to 4 times per second, while the aluminum-alloy body weighs 400 g and can be mounted singly or grouped on an integrated manifold base.

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.

A stopper cylinder on a bottle conveyor must stay extended until the next batch is cleared. The memory function keeps the gate in its last pulsed position through a control-power dip, and Cv 1.65 fills an O63 bore quickly between bottles.
Fixture clamps on a machining center hold their state if the PLC drops out mid-cycle, which this double-solenoid design does without holding current. The 28.0 mm2 effective area suits O50-80 mm clamp bores and the 0.05 s response keeps index times short.
Ejector cylinders on an injection molding machine run millions of short, fast strokes. This valve cycles up to 4 times per second, and the AC220V coil draws only 4.5 VA, keeping coil heating low across long production shifts.
Step down to the 4V200 body (Cv 1.0) when the cylinder is a smaller ~O40 bore and fill rate is not critical; step up to the 4V400 body (Cv 2.82) for ~O100+ rams that need more flow. Choose the single-solenoid 4V310 if a spring-return fault position is preferred, or a 4V330C/E/P 5/3 valve if the cylinder must hold, float or stay pressurized at center. One manifold base can carry a whole group of 4V300 valves on multi-station machines. When replacing an existing unit, match five points exactly: body size 4V300, function 20 (double solenoid), port 3/8in with G (BSPP) thread, coil voltage AC220V, and electrical entry terminal box - not the I-suffix grommet lead with 0.5 m flying wire.
Quick checklist
Effective area 28.0 mm2 (Cv 1.65) on both positions, maximum frequency 4 cycles per second, response time 0.05 s or less, working pressure 0.15-0.8 MPa with 1.2 MPa proof pressure, AC220V coil at 4.5 VA, IP65 protection, and a 400 g aluminum-alloy body. Supply air must be filtered by a 40 um element, and lubrication is not required.
No. The spool simply stays in its last pulsed position, held by land friction and balanced pressure with no spring and no holding current. That is useful for process continuity but is not a certified holding device. For suspended or hazardous loads, add pilot-operated check valves at the cylinder ports or a dedicated mechanical brake.
