The AirTAC Airtac 4V Solenoid Valves 4V330C10AG-W is a genuine 5/3-way 5/3 double solenoid — closed center solenoid valve with W ports and an effective area of 21.3 mm² (Cv 1.25). It is an internally piloted spool valve that directs compressed air to double-acting cylinders and actuators.
The 4V330C10AG-W is an AirTAC 4V300 series 5/3-way double-solenoid valve with a closed-center spool, an AC220V coil drawing 4.5 VA, terminal-box wiring and 3/8" G (BSPP parallel) ports. When both coils are off, the closed center blocks supply, exhaust and both cylinder ports at once, so a double-acting cylinder pauses and stays where it was pulsed - exactly what a slide or press ram needs between strokes. Flow capacity is Cv 1.25 with a 21.3 mm2 effective area, which fits double-acting cylinders of roughly Dia50-80 mm. Activation takes 0.05 s or less and the valve switches up to 3 cycles per second. The aluminium-alloy body weighs 450 g, runs on air filtered by a 40 um element at 0.15-0.8 MPa, and can mount singly or in an integrated manifold group on a shared 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.

On a Dia63 mm bench punch, the closed center parks the ram under power between strokes; Cv 1.25 refills the bore quickly enough to keep pace with the 3 cycles per second this valve allows.
A vertical lift gate on a packaging machine stops level mid-travel whenever both coils drop out. For a permanently suspended load, fit a pilot-operated check valve at the cylinder ports - the center position alone is not a certified brake.
Holds a Dia80 mm swing clamp extended while the cutter runs. The 3/8" G ports accept a manifold base, so the whole fixture row shares one air preparation and wiring station.
Size in both directions before ordering. Step down to the 4V200 (Cv 1.0) if your bore sits nearer Dia40 mm and the flow class is oversized; step up to the 4V400 (Cv 2.82) once bores pass Dia80 mm and stroke speed suffers. Among functions, pick this closed center when the actuator must stop and hold mid-stroke, the exhaust center when it should float free, or a 5/2 memory valve when only two end positions exist. A single valve threads straight into the G ports; a manifold base lets a whole valve bank share one supply and one wiring point. For a like-for-like swap, match all five points: body size (4V300), function (30C closed center), port and thread (3/8", G), coil voltage (AC220V) and electrical entry (terminal box).
Quick checklist
Flow is Cv 1.25 with a 21.3 mm2 effective area; response is 0.05 s or below and the switching rate tops out at 3 cycles per second. Operating pressure spans 0.15-0.8 MPa with 1.2 MPa proof pressure. The AC220V coil draws 4.5 VA, protection is IP65 (DIN40050) with class B insulation, the body weighs 450 g, and the air supply must be filtered to 40 um. Working temperature range is -20 to +70 C, and lubrication is not required.
Function and ports carry over - all three are closed-center 5/3 valves with 3/8" G ports and terminal entry - but the coil differs, so check the control cabinet first. The -10BG runs DC24V at 3.0 W, the -10AI runs AC220V at 4.5 VA in a grommet body with a 0.5 m flying lead instead of a terminal box. Match body size, function, port and thread, voltage and entry style before substituting anything.
