About the AirTAC 4V320-10F Solenoid Valve, 5/2-way, PT3/8, DC12V, terminal entry (4V32010F)
The AirTAC 4V320-10F is a 5/2-way double-solenoid directional control valve built on the 4V300 body, directing compressed air to double-acting cylinders and rotary actuators. Its defining feature is a memory spool: a momentary pulse to either solenoid shifts the valve, and the spool stays locked in that last-commanded position even when power is completely removed—no spring, no holding current, just balanced pressure and land friction. This makes it ideal for applications where the actuator must hold its end-of-stroke state without continuous coil energisation.
With a 3/8-inch PT port, a DC12V coil drawing just 2.5 W, and a terminal-box electrical entry, this valve suits moderate-flow circuits where low-voltage DC control is preferred. The 4V300 body delivers an effective area of 28.0 mm² (Cv 1.65) and can cycle at up to 4 times per second, providing crisp response for cylinders in the ~O50–80 mm bore range. The aluminium-alloy body weighs 400 g, carries an IP65 protection rating, and operates reliably from 0.15 to 0.8 MPa without requiring lubrication.

Where the AirTAC 4V320-10F Solenoid Valve, 5/2-way, PT3/8, DC12V, terminal entry (4V32010F) Is Used
Packaging & Palletising
Drives clamp and pusher cylinders on case packers and palletisers. The memory spool keeps the tooling in its last position during a machine pause or E-stop, so the sequence can resume without a re-homing cycle.
Low-Voltage Mobile Equipment
The DC12V coil and 2.5 W draw suit battery-powered lift tables, mobile compactors, and service-vehicle tooling. The double-solenoid memory holds the actuator position without draining the battery.
Pulse-Controlled Gate Valves
Operates large slide gates and diverter flaps in bulk-material handling. A brief 12 V pulse opens or closes the gate; the valve holds the spool position, so the gate stays put even if the control panel loses power.
Is the AirTAC 4V320-10F Solenoid Valve, 5/2-way, PT3/8, DC12V, terminal entry (4V32010F) the Right Valve?
Choose the 4V320-10F when your circuit needs a 5/2 double-solenoid valve with a 3/8-inch port and a 12 V DC supply. The memory function is the key differentiator from the spring-return 4V310: if you want the actuator to stay put after a short control pulse—without heating the coil or draining a battery—this is the correct configuration. The 3/8-inch port (Cv 1.65) fits cylinders roughly O50–80 mm; for smaller bores around O32–40 mm, stepping down to a 4V200 series (Cv 1.0) can save space and cost, while larger O100–125 mm cylinders usually demand the higher flow of a 4V400 (Cv 2.82).
When replacing an existing valve, match five points exactly: body size (4V300), function (double solenoid 5/2), port and thread (3/8 PT), coil voltage (DC12V), and electrical entry (terminal box). If you plan to group several valves on a common supply and exhaust, specify the 4V300 manifold base and confirm the station pitch. For a 5/3 center position—closed, exhaust, or pressure—switch to a 4V330x model, noting that the effective area drops to 21.3 mm² (Cv 1.25).
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 4V320-10F Solenoid Valve, 5/2-way, PT3/8, DC12V, terminal entry (4V32010F) FAQ
The spool stays in the position it was last pulsed to—it does not spring back. The cylinder will remain pressurised on one side and hold its end-of-stroke position. This is a memory function, not a safety-rated load brake; if you are holding a suspended load, add a pilot-operated check valve at the cylinder ports.
No—the 4V320-10F is wound specifically for DC12V (2.5 W). Applying 24 V will overheat the coil and burn it out quickly. For a 24 V DC supply, order the 4V320-10B instead; it is mechanically identical but uses a 3.0 W DC24V coil.
