The AirTAC Airtac 4V Solenoid Valves 4V330C10AG is a genuine 5/3-way 5/3 double solenoid — closed center solenoid valve with 330C10AG 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 AirTAC 4V330C-10AG is a 5/3-way double-solenoid valve with a closed center, built to send compressed air to double-acting cylinders and pneumatic actuators that need to pause mid-stroke. Each solenoid pulse shifts the spool and drives the cylinder; when both coils are off, all five ports are blocked, so a bore in the ~Dia50-80 mm class simply freezes where it stopped. This exact SKU is wired for AC220V mains (4.5 VA coil) through a terminal box, with G (BSPP parallel) 3/8" inlet, outlet and cylinder ports - the 1/4" exhaust keeps silencer and muffler fittings compact. Performance-wise you are in the 21.3 mm2 (Cv 1.25) flow class, which moves enough air for 3 cycles per second on the larger 4V300 body. Spool response on activation is 0.05 s or less, the aluminum-alloy body weighs 450 g, and the valve runs on 0.15-0.8 MPa of clean air (40 um filtration) from -20 to +70 C with IP65 (DIN40050) coil protection. A locking or non-locking manual override lets you jog the actuator during commissioning, and the body bolts onto a common base to build an integrated manifold group for multi-station machines.

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 vertical pick arm with a Dia63 cylinder (about 156 kgf push at 0.5 MPa) lowers cheese blocks into trays. The closed center blocks both cylinder ports at the null position, so the arm dwells between stations without drifting, at cycling rates within the valve's 3 c/s limit.
A Dia80 bore carriage carries a hot-melt glue head across box seams. Cv 1.25 flow fills the larger bore quickly, and the closed center parks the head precisely between cartons so the operator can clear a jam without the carriage sliding.
Two clamp arms on a robotic weld fixture for bracket assemblies are toggled by one 5/3 valve. During part loading the technician de-energises both coils; the arms hold wherever they stopped, and the <=0.05 s response snaps the sequence back the instant a pulse arrives.
Size in both directions before ordering. If your cylinder is a Dia40-50 bore producing roughly 62-98 kgf at 0.5 MPa, the 4V200 series 5/3 valves (Cv 1.0) shift faster and cost less. If you are moving a Dia100 bore (about 392 kgf push at 0.5 MPa) or need faster cycling than this valve's 3 c/s, step up to the 4V400 body with its Cv 2.82. Within the 4V300 line, choose the 30C closed center (this valve) when the actuator must dwell and hold between positions, the 30E exhaust center when the cylinder should float free, or the 30P pressure center when both sides should stay live; a 4V320 5/2 double-solenoid valve is the simpler choice if no mid-position is ever needed. A single standalone valve suits one actuator; order the manifold base version when several stations share one supply. For a like-for-like replacement, match all five points: body size (4V300), function code (30C), port and thread (3/8" in G/BSPP), coil voltage (AC220V), and electrical entry (terminal box, not the I grommet with 0.5 m lead).
Quick checklist
Flow: effective area 21.3 mm2, Cv 1.25, maximum 3 cycles per second. Pressure: 0.15-0.8 MPa working, 1.2 MPa proof. Response: activating time 0.05 s or less. Coil: AC220V at 4.5 VA on a terminal-box entry, IP65 (DIN40050) protected, insulation class B. Body: aluminum alloy, 450 g, G (BSPP) 3/8" inlet, outlet and cylinder ports with 1/4" exhaust. Operating temperature -20 to +70 C with air filtered to 40 um, no lubrication required.
No. The closed center blocks the cylinder ports, so a Dia50-80 mm bore normally stays put between commands - that is a positioning dwell, not a certified brake. Spool leakage, supply fluctuations or hose failure can allow slow drift, especially with vertical or overhanging loads. For any suspended-load or fall-protection duty, pair this valve with pilot-operated check valves at the cylinder ports or a dedicated mechanical brake; treat the valve's center position as control convenience only.
