About the AirTAC 4V330E-10 Solenoid Valve, 4V300 Series (4V330E10A-W)
This AirTAC 4V330E10A-W is a 5/3-way valve with two solenoids and an exhaust-center spool, mounted on the 4V300 body with 3/8-inch PT tapered ports. Each coil pulse shifts the spool to direct air to one side of a double-acting cylinder while the other side vents; when both coils are off, the spool rests in the center position where the two cylinder ports A and B are opened to exhaust. That means the connected actuator floats free at rest - it can be nudged, positioned or unloaded by hand or by an external force, which is exactly what setup and loading stations need.
The numbers behind it: 21.3 mm2 effective area (Cv 1.25), a maximum of 3 cycles per second, response in 0.05 s or less, and a 450 g body that suits double-acting cylinders in the rough O50-80 mm bore range. This specific SKU pairs the AC220V coil drawing 4.5 VA with a terminal-box entry and PT threading. The -W suffix marks it as the external-pilot build: pilot air is supplied through a dedicated external port instead of being bled from the main line inside the valve, so shifting stays dependable on mains where pressure runs low, fluctuates, or sits in vacuum territory.

Where the AirTAC 4V330E-10 Solenoid Valve, 4V300 Series (4V330E10A-W) Is Used
Low-pressure and vacuum handling lines
Because pilot air comes in through its own external port, the 4V330E10A-W keeps shifting cleanly on mains that sag or run under vacuum, where an internally piloted valve would stick mid-stroke.
Machine-tool setup and fixture stations
The exhaust center vents both cylinder lines at rest, so slides and clamps can be repositioned freely during changeover; one coil pulse then restores the working circuit instantly.
Transfer and lift units on mid-size bores
Double-acting cylinders around O50-80 mm get Cv 1.25 of flow with sub-0.05 s response, enough for moderate-speed pallet and workpiece transfer on a 3/8-inch PT circuit.
Is the AirTAC 4V330E-10 Solenoid Valve, 4V300 Series (4V330E10A-W) the Right Valve?
Size against your bore first. If your cylinder is small and flow demand is light, the 4V200 family (Cv 1.0) costs less and does the job; if you move up to larger bores, step to the 4V400 (Cv 2.82). This 4V300 sits in between at Cv 1.25 for the 5/3 version - note the center-exhaust trim carries a smaller area and a 3 c/s limit than the 5/2 models in the same body, so check cycle speed against your application. Pick the center type deliberately: closed center (30C) locks the cylinder in place, exhaust center (30E, this valve) lets it float, pressure center (30P) holds both sides live. A single valve suits one station; add a manifold base when you want several valves ganged on one supply.
When replacing, match all five points: body size (4V300), function (5/3 exhaust center), port and thread (3/8-inch, PT tapered), coil voltage (here AC220V at 4.5 VA), and electrical entry (terminal box). If your circuit runs on low or unstable main pressure, keep the -W external-pilot option rather than a standard internally piloted valve.
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 4V330E-10 Solenoid Valve, 4V300 Series (4V330E10A-W) FAQ
It is a 5/3-way valve for double-acting cylinders and pneumatic actuators - never single-acting types, which need a 3/2 valve. Flow capacity is 21.3 mm2 effective area (Cv 1.25), suited to bores of roughly O50-80 mm, with switching in 0.05 s or less and up to 3 cycles per second. Ports are 3/8-inch PT on inlet and outlet, with 1/4-inch exhausts.
De-energising both solenoids returns the spool to the exhaust-center position, venting cylinder ports A and B so the actuator floats free for manual adjustment or unloading. The -W build feeds pilot air from a separate external port rather than the main line, keeping shifting reliable at low or unstable supply pressure. One caution: a floating or center-position valve is not a load brake - for suspended or hazardous loads, add a pilot-operated check valve at the cylinder ports or a mechanical brake.
