About the AirTAC 4V420-15EI Solenoid Valve, 5/2-way, PT1/2, AC24V, grommet entry (4V42015EI)
The 4V420-15EI directs compressed air to large double-acting cylinders, using a dual-solenoid memory design that holds the spool in its last pulsed position without continuous current. When power is removed, the valve stays put—ideal for processes where a signal loss should not shift the actuator.
This 4V400 body model delivers a 48.0 mm² effective area (Cv 2.82) and suits bore sizes around Ø80–125 mm. The AC24V coil draws 5.0 VA and the grommet entry provides a 0.5 m pre-wired flying lead. Response time is 0.05 s or below, and the aluminum body weighs 720 g.

Flow & Coil Options
| Effective area | 48.0 mm² |
|---|---|
| Flow coefficient | Cv 2.82 |
| Response time | ≤ 0.05 s |
| Coil power | AC 4.5 VA · DC24V 3.0 W · DC12V 2.5 W |
| Protection / insulation | IP65 (DIN40050), B-class |
| Voltage options | DC24V, DC12V, AC110V, AC220V |
| Manual override | Yes (locking / non-locking) |
Size the valve so effective area / Cv is not the bottleneck for your cylinder bore and speed. Undersized valves slow the actuator. Note 5/3 (center) versions have a smaller effective area than the 5/2 of the same body size.

Where the AirTAC 4V420-15EI Solenoid Valve, 5/2-way, PT1/2, AC24V, grommet entry (4V42015EI) Is Used
Large Part Transfer
Controls a transfer arm on a conveyor line. The memory function keeps the arm extended if a stop signal occurs, preventing the part from dropping mid-cycle.
Wood Processing Clamp
Operates a heavy clamping fixture in a sawmill. The double-solenoid hold maintains clamping force on the timber even if the control panel is powered down between cuts.
Material Hoist Gate
Drives a gate on a bulk material hopper. The valve’s memory holds the gate open or closed without coil heating, and the AC24V supply is common in building services panels.
Is the AirTAC 4V420-15EI Solenoid Valve, 5/2-way, PT1/2, AC24V, grommet entry (4V42015EI) the Right Valve?
Choose the 4V420-15EI when you need a 5/2 double-solenoid valve that holds position on power loss without a spring return. For smaller cylinders around Ø63 mm, step down to the 4V300 series (Cv 1.65) to avoid oversizing. The 4V400 is the largest 4V body; if you need still-higher flow, consider a larger valve series or manifold.
When replacing an existing valve, match five points: body size (4V400), function (double solenoid 5/2), port and thread (1/2 in, PT), coil voltage (AC24V), and electrical entry (grommet with flying lead). This ensures drop-in compatibility.
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 4V420-15EI Solenoid Valve, 5/2-way, PT1/2, AC24V, grommet entry (4V42015EI) FAQ
With a Cv of 2.82 and 48.0 mm² effective area, it suits double-acting cylinders in the Ø80–125 mm range. It provides ample flow for rapid cycling of large actuators without excessive pressure drop.
A momentary pulse to coil 14 shifts the spool; a pulse to coil 12 shifts it back. The spool is held in place by land friction and balanced pressure—no spring, no holding current, and no magnetic latch. On full power loss, it stays in the last commanded position.
