The AirTAC Airtac 4V Solenoid Valves 4V12006BG is a genuine 5/2-way double solenoid (memory) solenoid valve with 12006BG ports and an effective area of 10.2 mm² (Cv 0.6). It is an internally piloted spool valve that directs compressed air to double-acting cylinders and actuators.
The AirTAC 4V120-06BG is a compact 5/2 double-solenoid valve that switches compressed air between the two sides of a double-acting cylinder or rotary actuator. Because both positions are solenoid-pulsed, the spool simply stays where it was last commanded: land friction and balanced pressure hold it, with no spring and no holding current. The retention is mechanical, not magnetic latching - a distinction that matters when you specify around interrupted power. This G-thread SKU carries 1/8in BSPP parallel ports, a DC24V coil drawing 2.8 W and a terminal-box entry for fixed panel wiring. Flow sits at 10.2 mm2 effective area (Cv 0.6), a match for double-acting cylinders in the Dia 16-32 mm range. Response time is 0.05 s or less, the aluminium body weighs 175 g, and the valve can be ganged onto a manifold base when your panel grows.

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.

The 0.05 s response opens and closes a Dia 20 mm parallel gripper between tray transfers, and the memory hold keeps the grip state if the 24 V rail dips mid-cycle.
A small assembly dial indexed every 0.6 s stays within the 5 cycles/s limit, and Cv 0.6 feeds the short rotation of a Dia 25 mm actuator without starving its speed.
On a benchtop drilling fixture, a Dia 32 mm double-acting clamp slide is pulsed from a 24 V PLC output; the 2.8 W coil keeps panel load and heat low, with a locking manual override for setup.
Step up to the 4V200 body (Cv 1.0) if your cylinder exceeds Dia 32 mm or the cycle demands more speed; on short strokes at Dia 16-25 mm this 4V100 flow class is already generous. If you would rather the valve spring back whenever power drops, the single-solenoid 4V110-06 in the same body is the neighbour to drop to, with the same Cv 0.6. When a mid-stroke stop is needed instead, the closed-center 5/3 version 4V130C trades flow for holding: 8.6 mm2 / Cv 0.51 and 3 cycles/s rather than 5. Mount singly for spot use or on a manifold base to gang several stations. For a replacement, match all five points: 4V100 body, function 20, 1/8in port with G (BSPP) thread, DC24V coil and terminal entry.
Quick checklist
It is a 5/2 double-solenoid, internally or externally piloted valve with 10.2 mm2 effective area (Cv 0.6), a maximum of 5 cycles per second and a response time of 0.05 s or less. Working pressure spans 0.15-0.8 MPa with 1.2 MPa proof pressure, temperature -20 to +70 C, and the air must be filtered by a 40 um element. The DC24V coil draws 2.8 W, entry is a terminal box, protection is IP65 (DIN40050), insulation class B, lubrication is not required, and the aluminium body weighs 175 g.
Yes - once pulsed, the spool stays in its last position through land friction and pressure balance; there is no return spring and no magnetic latch, so no holding current is consumed. That is ideal for keeping a jig or slide still through an interrupted cycle, but it is not a certified brake. For suspended or fall-hazard loads, add a pilot-operated check valve at the cylinder ports or a dedicated mechanical brake alongside this valve.
