About the AirTAC 4V320-08F Solenoid Valve, 5/2-way, PT1/4, DC12V, terminal entry (4V32008F)
The AirTAC 4V320-08F is a 5/2-way double-solenoid pneumatic directional valve built on the 4V300 aluminum body platform. It directs compressed air to double-acting cylinders and actuators, and its memory function means the spool stays locked in the last pulsed position when electrical power is removed—no spring return, no holding current. This makes it ideal for circuits where the actuator must hold its end-of-stroke position during an E-stop or power cycle, though a pilot-operated check valve is still required for true load-holding safety.
With 1/4-inch PT (Rc) ports and a DC12V coil drawing just 2.5 W, this valve suits compact mobile or battery-powered pneumatic systems. The sliding-column spool delivers an effective area of 28.0 mm² (Cv 1.65) and a maximum cycling rate of 4 cycles per second. Response time is 0.05 seconds or less, and the IP65-rated terminal-box entry keeps the wiring protected in dusty or wet environments. At 400 grams, it’s a robust yet manageable choice for machine builders.

Where the AirTAC 4V320-08F Solenoid Valve, 5/2-way, PT1/4, DC12V, terminal entry (4V32008F) Is Used
Packaging & Palletizing
The memory function holds clamp or pusher cylinders in place during a power interruption, preventing product damage on a palletizer or case packer. The 4 c/s max frequency keeps up with moderate-speed packaging lines.
Machine Tool Clamping
A double-solenoid 5/2 valve ensures a fixture clamp stays engaged when the machine E-stops. The 1/4-inch ports and Cv 1.65 provide ample flow for medium-bore clamping cylinders.
Battery-Powered Mobile Equipment
The 2.5 W DC12V coil draws minimal current from a vehicle or battery supply. Use it to control gate or chute actuators on agricultural or construction equipment where wiring simplicity matters.
Is the AirTAC 4V320-08F Solenoid Valve, 5/2-way, PT1/4, DC12V, terminal entry (4V32008F) the Right Valve?
Choose the 4V320-08F when your application needs a 5/2 valve that remembers its last state without continuous power—perfect for energy-sensitive or safety-conscious circuits. The 1/4-inch port size and 28.0 mm² effective area suit double-acting cylinders roughly in the Ø50–80 mm range. If you’re driving a smaller cylinder (Ø32–40 mm), the 4V200 series (Cv 1.0) may be a better fit; for larger bores above Ø100 mm, step up to the 4V400 (Cv 2.82) for faster fill times.
When replacing an existing valve, match these five points exactly: body size (4V300), function (4V320 double-solenoid memory), port and thread (1/4-inch PT), coil voltage (DC12V), and electrical entry (terminal box). This valve can be used as a single unit or ganged on a manifold base—the manifold option simplifies plumbing for multi-cylinder stations. The DC12V coil is less common than DC24V, so verify your power supply before ordering.
Quick checklist
- ✓ Required flow (Cv) for cylinder & speed
- ✓ Function: single / double / 5-3 center

- 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 4V320-08F Solenoid Valve, 5/2-way, PT1/4, DC12V, terminal entry (4V32008F) FAQ
The double-solenoid spool stays in its last commanded position—it does not spring back. The cylinder will hold its current state until the opposite solenoid is pulsed. This is a mechanical memory hold, not a magnetic latch. For suspended loads, always add a pilot-operated check valve.
Yes, the ‘F’ voltage code is specifically for DC12V coils. Power consumption is 2.5 W, so it’s well-suited to mobile or off-grid pneumatic setups. Just ensure your supply can handle the inrush when the coil energizes.
