About the AirTAC 4V330P-10 Solenoid Valve, 4V300 Series (4V330P10B-AM)
The AirTAC 4V330P10B-AM is a 5/3-way double-solenoid directional valve with a pressure center: at rest both cylinder ports A and B stay connected to supply pressure, keeping both sides of a double-acting cylinder charged. It switches on a brief pulse to either solenoid and stays in that last position with no holding current, while the pressured center keeps the actuator ready to move the moment a new command arrives.
Built on the 4V300 body, this 3/8in PT-threaded version flows through an effective area of 21.3 mm2 (Cv 1.25) - the figure for 5/3 valves in this class - and pairs naturally with double-acting cylinders of roughly O50-80 mm bore. The -AM suffix means this unit ships with an Italian AMISCO solenoid coil instead of the standard one; the ordered DC24V voltage still applies, and you should confirm the exact AMISCO coil rating with us before wiring. Terminal-box entry, response time of 0.05 s or better, and a 450 g valve weight round out the specification.

Flow & Coil Options
| Effective area | 21.3 mm² |
|---|---|
| Flow coefficient | Cv 1.25 |
| Response time | ≤ 0.05 s |
| Coil power | AC 4.5 VA · DC24V 3.0 W · DC12V 2.5 W |
| Protection / insulation | IP65 (DIN40050), B-class |
| Voltage options | DC24V, DC12V, AC110V, AC220V |
| Manual override | Yes (locking / non-locking) |
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.

Where the AirTAC 4V330P-10 Solenoid Valve, 4V300 Series (4V330P10B-AM) Is Used
Machine tool slide positioning
A pressured center keeps both sides of a double-acting slide cylinder charged between commands, so the slide does not drift while the machine waits for the next move - and the valve re-issues full flow in 0.05 s or less.
Press and forming fixtures
Both-workport pressurisation at center suits clamping and forming tools that benefit from both cylinder chambers being held under pressure during a pause in the cycle, on cylinders in the ~O50-80 mm range.
Multi-valve manifolds on DC control
Pulsed DC24V operation with terminal-box wiring and the option to group on a manifold base makes this AMISCO-coil valve practical for PLC-driven stations where several 5/3 valves sit side by side.
Is the AirTAC 4V330P-10 Solenoid Valve, 4V300 Series (4V330P10B-AM) the Right Valve?
Choose the 4V330P10B-AM when your double-acting cylinder sits in the mid-size band around O50-80 mm: the 21.3 mm2 (Cv 1.25) orifice of the 5/3 4V300 class covers it well. If your bore is smaller and you do not need a three-position center, the 4V200 (Cv 1.0) is the more economical step down; for bores above roughly O80 mm, move up to the 4V400 (Cv 2.82). Among three-position centers, pick pressure center (this valve) when both cylinder sides should stay pressurised at rest, exhaust center when the actuator should float freely, and closed center when ports must be blocked.
For replacement, match all five points: 4V300 body, 5/3 pressure-center function (30P), 3/8in PT port, DC24V coil, and terminal entry - plus confirm you want the AMISCO-coil -AM option, since 4V330P-10B without the suffix is a distinct part. A single valve mounts directly, or several can share a manifold base for compact multi-valve stations.

- check Use the manual override to test before powering.
- check Fit silencers or fittings to the exhaust ports.
- check Wiring by qualified personnel per AirTAC docs.
AirTAC 4V330P-10 Solenoid Valve, 4V300 Series (4V330P10B-AM) FAQ
It means the valve leaves the factory with an Italian AMISCO solenoid coil fitted in place of the standard AirTAC coil. The body, 5/3 pressure-center function, 3/8in PT ports and DC24V operating voltage are unchanged. Because our published 3.0 W figure applies to the standard DC24V coil, please confirm the exact AMISCO coil rating with us before ordering or wiring.
No. The pressure center keeps both cylinder ports connected to supply, which is a positioning and standby behavior, not a positive lock. For guaranteed holding of a suspended or falling load, fit a pilot-operated check valve at the cylinder ports or a dedicated mechanical brake - the valve alone must not be relied on as a safety device.
