About the AirTAC 4V320-08FI Solenoid Valve, 5/2-way, PT1/4, DC12V, grommet entry (4V32008FI)
The 4V320-08FI is a 5/2-way double-solenoid pneumatic directional valve from the AirTAC 4V300 series, designed to command double-acting cylinders and actuators with a memory-hold function. Its spool stays in the last pulsed position when power is removed—held by land friction and balanced pressure, not by a spring or magnetic latch—making it ideal for sequences that must persist through an E-stop or power cycle without a constant holding signal.
This specific configuration ships with a DC12V coil (2.5 W power draw), a grommet-style electrical entry with a 0.5 m flying lead for DIN-rail wiring, and 1/4-inch PT (Rc) tapered ports. With an effective area of 28.0 mm2 (Cv 1.65) and a response time of 0.05 s or less, it comfortably drives cylinders in the ~O50-80 mm bore range at up to 4 cycles per second.

Where the AirTAC 4V320-08FI Solenoid Valve, 5/2-way, PT1/4, DC12V, grommet entry (4V32008FI) Is Used
Material-Handling Gates
A diverter gate on a conveyor driven by a 63 mm bore cylinder needs to stay put if a line-stop is triggered. The 4V320-08FI memory spool holds the gate position without power, preventing product spillage and allowing a controlled restart.
Clamp & Hold Fixtures
In a CNC pallet-changing station, a double-acting clamp must remain locked during tool changes even when the solenoid signal drops. The 4V320-08FI’s 28.0 mm2 effective area provides fast clamping force, and the memory function keeps the fixture secure without coil heating.
12 VDC Mobile & Battery Systems
Mobile hydraulic-pneumatic hybrid units often run on 12 VDC battery power. The 2.5 W DC12V coil and grommet-style flying lead of the 4V320-08FI simplify wiring into a sealed control box, while the 1/4-inch port fits compact hose layouts.
Is the AirTAC 4V320-08FI Solenoid Valve, 5/2-way, PT1/4, DC12V, grommet entry (4V32008FI) the Right Valve?
Choose the 4V320-08FI when your application needs a 5/2 double-solenoid valve that holds its last spool position without continuous power, and you are wiring into a 12 VDC control cabinet with a DIN-style grommet lead. The 1/4-inch PT port matches many compact manifold bases and mid-size cylinders; if you need a larger flow path for an O80+ bore, step up to the 4V400 series (Cv 2.82), and for smaller O32-40 mm cylinders the 4V200 (Cv 1.0) is a better fit.
When replacing an existing valve, match all five points: body size (4V300), function (20 = double solenoid memory), port and thread (1/4-inch PT), coil voltage (DC12V), and electrical entry (grommet with flying lead). The 4V300 family also supports integrated manifold bases—order the valve and base together if you are building a multi-station bank.
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 4V320-08FI Solenoid Valve, 5/2-way, PT1/4, DC12V, grommet entry (4V32008FI) FAQ
With a Cv of 1.65 (28.0 mm2 effective area), it is sized for double-acting cylinders roughly in the O50-80 mm bore range. It can cycle at up to 4 times per second. For a larger O100 mm cylinder running at high speed, consider moving up to the 4V400 series (Cv 2.82).
No. The spool holds its last position through friction and pressure balance, not a mechanical lock. If the application involves a suspended or vertical load where drift could be dangerous, you must add a pilot-operated check valve at the cylinder ports or a dedicated mechanical brake—the valve alone is not a safety holding device.
