About the AirTAC 4V420-15
The AirTAC 4V420-15 is a 5/2-way pilot-operated spool valve on the 4V400 body with 1/2" working ports. It is a double-solenoid valve with memory: a short pulse on either coil shifts the spool and it stays there, even if power is lost, until the other coil is pulsed.
The 4V420-15 has an effective area of 48.0 mm² (Cv 2.82), a maximum frequency of 3 cycles per second and weighs about 720 g. It works from 0.15 to 0.8 MPa on air filtered to 40 µm, needs no lubrication, responds in 0.05 s or less, and its coil is rated IP65 with class B insulation. A manual override is fitted, and valves can be mounted on a manifold base.

Where the 4V420-15 Is Used
Cylinder control
Drives double-acting cylinders: the 5/2-way layout switches supply between the two cylinder ports.
Holds on power loss
Memory keeps the last position through a power cut, useful for clamps and gates.
Manifold installations
4V400 valves share a manifold base footprint, so several valves can run from one supply.
Choosing the Right 4V420-15 Configuration
Choose the coil voltage to match your control circuit: DC24V (B), AC220V (A), AC110V (C), AC24V (E), DC12V (F).
Then the electrical entry. The standard terminal box takes your own cable through a gland. The I version has a grommet with a 0.5 m lead wire already attached.
Finally the port thread: PT is standard, G (BSPP) is marked G.
