About the AirTAC 4V320-08EI Solenoid Valve, 5/2-way, PT1/4, AC24V, grommet entry (4V32008EI)
The 4V320-08EI is a double-solenoid 5/2-way pneumatic directional control valve built on the AirTAC 4V300 aluminium body platform. It directs compressed air to both sides of a double-acting cylinder or rotary actuator, and its memory spool holds the last pulsed position without needing a constant electrical signal—the spool stays put through land friction and balanced pressure, so the cylinder remains in place even if power is interrupted.
This specific configuration ships with an AC24V coil drawing 5.0 VA, a DIN-style grommet entry with a 0.5 m pre-wired flying lead, and 1/4-inch PT (Rc tapered) ports on all ways. With an effective area of 28.0 mm2 (Cv 1.65) and a response time of 0.05 s or below, it suits double-acting cylinders in the ~O50-80 mm bore range running on filtered, non-lubricated air at 0.15-0.8 MPa.

Where the AirTAC 4V320-08EI Solenoid Valve, 5/2-way, PT1/4, AC24V, grommet entry (4V32008EI) Is Used
Indexing Conveyor Gates
A pulsed signal shifts the 4V320-08EI to extend a gate cylinder, and the memory spool holds it open or closed without continuous power, saving energy in material-routing systems.
Clamp-and-Dwell Fixtures
In CNC or welding jigs, the valve holds a double-acting clamp cylinder in its last position after a brief pulse, keeping the part secure while the machine runs the next cycle.
Two-Position Rotary Actuators
Drive a rack-and-pinion rotary actuator between two stops with short electrical pulses; the 4V320-08EI maintains the angle until the opposite coil is pulsed, ideal for diverters or turntables.
Is the AirTAC 4V320-08EI Solenoid Valve, 5/2-way, PT1/4, AC24V, grommet entry (4V32008EI) the Right Valve?
Choose the 4V320-08EI when your circuit needs a 5/2 valve that stays in its last commanded state after a pulse, eliminating the heat and energy of a continuously energised coil. The 4V300 body sits between the compact 4V200 (Cv 1.0) and the larger 4V400 (Cv 2.82); step down to the 4V200 for O32-40 mm cylinders, or move up to the 4V400 for bores above 100 mm. For a five-point replacement match, verify body size (4V300), function (20 = double solenoid 5/2), port size and thread (1/4-inch PT), coil voltage (AC24V), and electrical entry (grommet with flying lead). If you are building a multi-station manifold, confirm the base shares the same port size and thread.
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 4V320-08EI Solenoid Valve, 5/2-way, PT1/4, AC24V, grommet entry (4V32008EI) FAQ
With an effective area of 28.0 mm2 (Cv 1.65), this 4V300-series valve typically suits double-acting cylinders in the ~O50-80 mm bore range. For smaller O32-40 mm cylinders a 4V200 (Cv 1.0) is often a better match, while bores above 100 mm usually benefit from the higher flow of a 4V400 (Cv 2.82).
The double-solenoid spool holds its last shifted position through land friction and balanced pressure when power is removed, but it is not a safety-rated load-holding device. If the application involves a suspended or vertical load, add a pilot-operated check valve at the cylinder ports or a mechanical brake to guarantee safe holding in the event of a pressure drop.
