About the AirTAC 4V330C-10 Solenoid Valve, 4V300 Series (4V330C10B-W)
The AirTAC 4V330C10B-W is a 5/3-way double-solenoid valve with a closed center, built on the larger 4V300 body with 3/8-inch PT ports. The -W suffix marks the external-pilot version: pilot air is fed through a separate external pilot port rather than tapped internally from the main supply, so the spool keeps switching dependably even when line pressure is low or the circuit runs under vacuum or reduced supply. At the center position all five ports are blocked, which locks a double-acting cylinder in place. Flow capacity sits at 21.3 mm2 effective area (Cv 1.25) with switching up to 3 cycles per second, a class that suits cylinders of roughly O50-80 mm bore.
This exact SKU pairs a DC24V coil drawing 3.0 W with a conventional terminal-box entry, so you hard-wire it on site without a flying-lead pigtail. Response is 0.05 s or better, the aluminum body weighs 450 g, and the valve carries IP65 (DIN40050) protection with class B insulation. A manual override is fitted for setup and troubleshooting, and the unit mounts on a base for building an integrated manifold group.

Where the AirTAC 4V330C-10 Solenoid Valve, 4V300 Series (4V330C10B-W) Is Used
Mid-stroke press and positioning
Closed-center blocking parks a double-acting press or positioning cylinder between cycles, while the external pilot keeps switching reliable in circuits where main pressure fluctuates.
Fixture and clamp actuation
Larger O50-80 mm clamp cylinders on machining and assembly fixtures hold their stroke when the valve centers, with DC24V control fitting standard 24V machine I/O.
Low-pressure material handling
diverters, stops and lifters driven at reduced or variable supply pressure stay controllable because pilot air comes in independently through the external pilot port.
Is the AirTAC 4V330C-10 Solenoid Valve, 4V300 Series (4V330C10B-W) the Right Valve?
Match this valve's 21.3 mm2 / Cv 1.25 flow class to your cylinder: for bores around O50-80 mm it is the right size. A smaller actuator can step down to the 4V200 family (Cv 1.0), while a larger bore calls for the 4V400 (Cv 2.82). Choose this 5/3 closed-center type when the actuator must stop and hold mid-stroke; pick a 4V320 5/2 memory valve if you only need two positions, or a 4V310 single-solenoid spring-return valve where a constant electrical signal drives the stroke. External pilot (-W) is the correct choice when supply pressure can drop or the circuit sees vacuum; internal-pilot 4V330C models assume a healthy main supply.
For multi-valve panels, base-mount several 4V300 bodies into one manifold to share a common supply and reduce piping. When reordering, verify all five points: 4V300 body, 5/3 closed-center function (30C), 3/8-inch PT thread, DC24V coil, and terminal-box entry - plus the -W external-pilot option.
Quick checklist

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 (4V330C10B-W) FAQ
It directs compressed air to double-acting cylinders and actuators, with a 21.3 mm2 effective area (Cv 1.25) that suits bores of roughly O50-80 mm and switching up to 3 cycles per second. The -W external-pilot design feeds pilot air through a dedicated port instead of the main line, so switching stays dependable when supply pressure is low or the circuit runs under vacuum or reduced pressure.
At center, all ports are blocked, so the cylinder stops where it was - but blocked-port holding is not a certified safety function. For suspended or fall-hazard loads, back it up with a pilot-operated check valve at the cylinder ports or a dedicated mechanical brake. This SKU is also specified as a DC24V, 3.0 W coil with terminal-box entry on 3/8-inch PT threads - match all of these when replacing a 4V330C-10B-W.
