About the AirTAC 4V120-06EI Solenoid Valve, 5/2-way, PT1/8, AC24V, grommet entry (4V12006EI)
The 4V120-06EI is a 5/2-way double-solenoid valve from the compact AirTAC 4V100 series, designed to direct compressed air to small double-acting cylinders and rotary actuators. Its memory-hold function means the spool stays locked in its last pulsed position when electrical power is removed—held by balanced pressure and land friction, not by a spring or magnetic latch. This makes it ideal for applications where the actuator must remain in place during an E-stop or power cycle without needing a constant holding current.
This specific configuration arrives with a pre-wired AC24V grommet lead-out, drawing 4.0 VA and simplifying wiring in DIN-rail panels. With an effective area of 10.2 mm² (Cv 0.6) and a response time of0.05 s or less, it comfortably cycles small bore cylinders in the ~Ø16-32 mm range at up to5 cycles per second. The aluminum-alloy body weighs175 g and operates on filtered, non-lubricated air from0.15-0.8 MPa.

Where the AirTAC 4V120-06EI Solenoid Valve, 5/2-way, PT1/8, AC24V, grommet entry (4V12006EI) Is Used
Pick-and-Place Grippers
The memory function holds a small gripper closed on a part during a transfer move, even if the machine enters an E-stop, preventing drops without needing constant power to the coil.
Divert Gate Actuation
Pulse the valve to raise or lower a small divert gate on a benchtop conveyor. The gate stays in position after the pulse, allowing the control system to focus on other tasks.
Lab Automation Fixtures
Controls a double-acting clamp on a test fixture. The AC24V grommet wiring integrates neatly into lab control panels, and the valve holds clamping force during long-duration tests.
Is the AirTAC 4V120-06EI Solenoid Valve, 5/2-way, PT1/8, AC24V, grommet entry (4V12006EI) the Right Valve?
Choose the 4V120-06EI when your small automation cell needs a valve that holds its position without a continuous signal, reducing coil heat and energy use. The double-solenoid 5/2 design is a direct fit for tasks like clamping or gate actuation where the cylinder must stay extended or retracted during a machine pause. If your cylinder is larger than ~32 mm bore or you need faster cycling, step up to the 4V200 series for its higher Cv of1.0.
For a drop-in replacement, match five points: body size (4V100), function (double-solenoid 5/2), port and thread (1/8in PT), coil voltage (AC24V), and electrical entry (grommet with0.5 m flying lead). This model can also be mounted on a manifold base to build a compact, multi-station valve group.
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 4V120-06EI Solenoid Valve, 5/2-way, PT1/8, AC24V, grommet entry (4V12006EI) FAQ
Its10.2 mm² effective area (Cv0.6) suits double-acting cylinders roughly in the Ø16-32 mm range for typical automation speeds. For a specific speed check, calculate the cylinder's air consumption against this Cv, but it's a strong match for small clamps, grippers, and ejectors.
The spool stays in its last pulsed position through balanced pressure and friction, with no spring to return it. It is not a magnetic latch. For holding a suspended or vertical load, do not rely on the valve alone—add a pilot-operated check valve at the cylinder port or a mechanical brake to guarantee the load won't drift.
