About the AirTAC 4V320-10 Solenoid Valve, 4V300 Series (4V32010E-W)
The 4V32010E-W is a 5/2-way double-solenoid directional valve in AirTAC's 4V300 body class, built with the -W external-pilot option: pilot air arrives through a separate external port rather than being tapped from the main line, so the spool still shifts cleanly on circuits where supply pressure runs low or sits at vacuum level. It routes compressed air to a double-acting cylinder or actuator, and because it is a memory valve it stays in whichever position it was last pulsed to - the spool simply rests there through land friction and balanced pressure, with no spring and no holding current (it is not magnetically latched).
At 28.0 mm2 effective area (Cv 1.65) it suits roughly O50-80 mm bores, switching up to 4 cycles per second with a response of 0.05 s or better. This exact SKU pairs an AC24V coil drawing 5.0 VA with a terminal-box entry and PT (Rc tapered) 3/8in ports, in a 400 g aluminium body rated IP65 with manual override.

Flow & Coil Options
| Effective area | 28.0 mm² |
|---|---|
| Flow coefficient | Cv 1.65 |
| 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 4V320-10 Solenoid Valve, 4V300 Series (4V32010E-W) Is Used
Low-pressure and vacuum circuits
External pilot supply keeps the spool shifting dependably where an internally piloted valve would stall - ideal for vacuum handling lines and processes fed from a soft or variable main.
Press and clamp actuation
Cv 1.65 flow drives O50-80 mm double-acting press and clamp cylinders, and the memory hold keeps the last commanded stroke after the pulse ends without wasting coil power.
Material handling and gating
4 cycles per second and a 0.05 s response keep diverters, lifters and gate cylinders cycling briskly on packaging and conveyor systems.
Is the AirTAC 4V320-10 Solenoid Valve, 4V300 Series (4V32010E-W) the Right Valve?
Size by bore: drop to the 4V200 (Cv 1.0) for cylinders under about O50 mm, and step up to the 4V400 (Cv 2.82) when a larger bore needs more flow. On function, choose this double-solenoid memory valve when a pulsed signal should hold position without continuous coil power; pick the single-solenoid 4V310 when the cylinder must spring back on signal loss, or a 5/3 4V330 variant when you need closed, exhaust or pressure center behavior. Mount on an individual base or gang several bodies into an integrated manifold group. To replace an existing unit, match all five points: 4V300 body size, function (20), port and thread (3/8in PT), coil voltage (AC24V) and electrical entry (terminal) - plus the -W external-pilot arrangement.
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 4V320-10 Solenoid Valve, 4V300 Series (4V32010E-W) FAQ
It is a 5/2-way valve with 28.0 mm2 effective area (Cv 1.65), sized for double-acting cylinders around O50-80 mm bore. It pressurises one cylinder side while exhausting the other, switching up to 4 cycles per second.
Because pilot air is fed from a dedicated external port instead of the valve inlet, the spool still shifts when main-line pressure is low or the circuit runs at vacuum. Note that for suspended or fall-protection loads, the memory hold alone is not a certified brake - add a pilot-operated check valve or mechanical brake at the cylinder.
