About the AirTAC 4V330C-10 Solenoid Valve, 4V300 Series (4V330C10C-W)
The AirTAC 4V330C10C-W is a 5/3-way double-solenoid valve with a closed center, built on the 4V300 body with 3/8" PT ports. At center position all five ports are blocked, so a double-acting cylinder connected to ports A and B simply stops and holds wherever it was when the signal was removed. Both solenoids are momentary: pulse one to extend, pulse the other to retract, and the spool sits closed-center between commands. The -W suffix marks the external-pilot version - pilot air is piped to a separate pilot port instead of being tapped internally, so the spool keeps switching even when main-line pressure is low or the circuit runs under vacuum.
Flow capacity sits at 21.3 mm2 effective area (Cv 1.25), the 5/3 rating of this body class, with switching in 0.05 s or less and a 3 cycle/sec maximum. The AC110V coil draws 4.5 VA and lands in a terminal-box entry for fixed conduit wiring, and the complete valve weighs 450 g. This size suits roughly O50-80 mm double-acting cylinders where a mid-stroke hold is part of the cycle.

Where the AirTAC 4V330C-10 Solenoid Valve, 4V300 Series (4V330C10C-W) Is Used
Press and forming fixtures
Closed-center blocking pauses a double-acting press or forming cylinder at an intermediate position between pulses, letting the operator stage or inspect the work before completing the stroke.
Multi-position machine tool slides
Low or vacuum-assisted pilot circuits benefit from the -W external pilot feed, keeping slide and indexing cylinders switching reliably on machine tools where line pressure dips during heavy cuts.
Clamping on production lines
With a Cv 1.25 flow path and O50-80 mm cylinder coverage, this valve holds clamp cylinders in position at center while downstream stations cycle, wired through the terminal box into plant AC110V control.
Is the AirTAC 4V330C-10 Solenoid Valve, 4V300 Series (4V330C10C-W) the Right Valve?
Match your bore first: the 4V300 class (Cv 1.25 in 5/3 form) serves O50-80 mm cylinders well; drop to a 4V200 (Cv 1.0) below that range or step up to a 4V400 (Cv 2.82) for larger bores. Choose closed center (this valve) when the actuator must pause mid-stroke, exhaust center when it should float freely, or pressure center when both sides must stay supplied. A single valve suits one actuator; bolt several onto a manifold base to share one supply and cut plumbing. When replacing, verify all five points: 4V300 body, 5/3 closed-center function, 3/8" port with PT thread, AC110V coil, terminal entry - plus the external-pilot -W option.
Quick checklist
- ✓ Required flow (Cv) for cylinder & speed
- ✓ Function: single / double / 5-3 center
- ✓ Coil voltage (DC24 / AC220 …)
- ✓ Port thread (M5 / 1/8 / 1/4 / 3/8 / 1/2)
- ✓ Single valve or manifold base?
Installation & Wiring Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 0.8 MPa operating pressure.
- check Match coil voltage to your controller output.
- 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 4V330C-10 Solenoid Valve, 4V300 Series (4V330C10C-W) FAQ
It directs compressed air to double-acting cylinders and actuators in the O50-80 mm range, with a 5/3 flow rating of 21.3 mm2 (Cv 1.25). The -W external-pilot design feeds pilot air from a separate port rather than tapping the main supply, so switching stays dependable when main-line pressure runs low or the circuit operates in vacuum or low-pressure service.
At center the valve blocks all ports, so the cylinder stops mid-stroke - useful for staging and fixturing. For genuinely suspended or fall-risk loads, the valve alone is not a certified brake: add a pilot-operated check valve at the cylinder ports or a dedicated mechanical brake to guarantee holding against leakage and spool wear.
