About the AirTAC 4V330E-10 Solenoid Valve, 4V300 Series (4V330E10B-W)
The AirTAC 4V330E10B-W is a 5/3-way double-solenoid directional valve with an exhaust center, built for directing compressed air to double-acting cylinders and actuators. Energise one coil to send air to port A or B; remove both signals and the spool sits at center, where both cylinder ports are exhausted, so the cylinder can float and be moved freely by hand or by load. Its flow class in the 4V300 family is 21.3 mm² effective area (Cv 1.25) with cycling up to 3 cycles per second, a good match for bores around 50-80 mm.
This -W variant uses an external pilot: pilot air arrives through a separate port instead of being tapped internally from the main line, so switching stays dependable where main-line pressure runs low or in vacuum and low-pressure circuits. The DC24V coil draws just 3.0 W and connects through a terminal box. The aluminium-alloy body weighs 450 g, response is 0.05 s or better, and the IP65 housing with manual override tolerates -20 to +70 C on 0.15-0.8 MPa supply.

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 |

Where the AirTAC 4V330E-10 Solenoid Valve, 4V300 Series (4V330E10B-W) Is Used
Press and forming tooling
Cycling medium-bore press or clamp cylinders where operators want a neutral that unclamps the tooling, letting dies and fixtures be repositioned by hand between cycles.
Material handling and lifts
Powered rollers, gates and lift assists on conveyance lines - the exhaust center frees the actuator for manual jogging during setup, washdown or jam clearing.
Low-pressure and vacuum circuits
The external-pilot -W option keeps switching reliable where the main line pressure alone cannot drive an internally piloted spool - vacuum handling and low-pressure test rigs included.
Is the AirTAC 4V330E-10 Solenoid Valve, 4V300 Series (4V330E10B-W) the Right Valve?
Size the valve to the bore: step down to the 4V200 (Cv 1.0) for cylinders under roughly 50 mm, or move up to the 4V400 (Cv 2.82) when a larger bore needs more flow. If the machine never needs a floating position, a 5/2 valve gives more flow for the same body; pick 30C when the cylinder must hold at center or 30P when both sides should stay pressurised. One valve on a stand-alone base or a shared manifold block are both supported. When replacing, match all five points: body size (4V300), function (5/3 exhaust center), port and thread (3/8" PT here), coil voltage (DC24V), and electrical entry (terminal box) - 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 4V330E-10 Solenoid Valve, 4V300 Series (4V330E10B-W) FAQ
It is rated for double-acting cylinders and actuators in the 50-80 mm bore range, passing 21.3 mm² effective area (Cv 1.25) at up to 3 cycles per second. Note the exhaust center leaves both cylinder ports open at rest, so the actuator is unpowered and movable whenever both coils are off.
An internally piloted valve needs enough main-line pressure to shift its own spool. This -W build takes pilot air from a separate external port instead, so it switches dependably in low-pressure or vacuum service where internal tapping would fail. Otherwise the valve is the same 5/3 exhaust-center, DC24V, 3/8" PT unit - and remember the exhaust center is not a load lock: fit pilot-operated check valves or a mechanical brake where a suspended load must be secured.
