AirTAC 3V210-06 Solenoid Valve, 3V200 Series (3V21006NOBI)
The AirTAC AirTAC 3V210-06 Solenoid Valve, 3V200 Series (3V21006NOBI) is a genuine 3-port 2-position (3/2) solenoid valve with 1/8 in ports. A 3/2 valve either feeds its outlet or vents it to exhaust, so it suits single-acting cylinders, air blow, clamping, vacuum switching and pilot duty. We stock this code and confirm its published figures from the datasheet on request.

About the AirTAC 3V210-06 Solenoid Valve, 3V200 Series (3V21006NOBI)
The 3V21006NOBI is a 3-port, 2-position solenoid valve with a normally open initial state: with the coil de-energised, supply air passes to the outlet, and energising the DC24V coil shuts the outlet and vents it to exhaust. That reversed logic is exactly what many circuits need - anything that should keep receiving air when control power drops, such as a hold-open blast, a pilot signal or a vent-to-atmosphere line, starts from a normally open valve rather than a normally closed one. The 1/8in PT port and flying-lead entry are built into this code.
We stock the 3V21006NOBI as a genuine AirTAC part and ship it directly. The same body is available normally closed as well as normally open, across AC220V, DC24V, AC110V, AC24V and DC12V coils, with flying lead or DIN plug entry, and the 3V200M manifold bases carry several of these valves on one shared supply. Any datasheet figure you need - pressure, flow or coil power - we will read out to you from the manufacturer documentation on request.

What a 3/2 Valve Does
A 3/2 valve has three ports — supply, outlet and exhaust — and two states. It either feeds the outlet or vents it to exhaust, and that is the whole job.
That makes it the right valve for a single-acting (spring-return) cylinder, on/off air blow, a clamp, switching a vacuum generator or suction cup, and piloting a larger valve.
It cannot run a double-acting cylinder. A double-acting cylinder needs air alternately on two sides, which takes a 5-port valve — the AirTAC 4V series.
Where the AirTAC 3V210-06 Solenoid Valve, 3V200 Series (3V21006NOBI) Is Used
Hold-open air assist on a packaging line
A belt of air that keeps a film web or a light flap lifted during a shift should not collapse every time an operator pauses the machine. A normally open 3/2 valve keeps the outlet fed through any power interruption and shuts the flow only when the control signal commands it.
Default-on chip-clearing jet on a CNC machining centre
Clearing swarf from a vice or a way cover between cycles is a job the valve does by simply being de-energised. With a normally open valve the jet runs whenever machine power is present, and the controller energises the coil to silence the blast at cycle end.
Fail-open pilot signal to a large process valve
Bigger pneumatic process valves often need a small pilot feed to hold a position. A normally open 3/2 valve keeps that pilot line supplied through a control power failure, so the process valve behaves the way your fail-safe design intends without extra logic.
Is the AirTAC 3V210-06 Solenoid Valve, 3V200 Series (3V21006NOBI) the Right Part?
Choose normally open when the safe or desired condition of your circuit is air flowing with power off; choose normally closed when the outlet should sit dead until the coil is energised. This SKU is the NO version, so on loss of DC24V the outlet stays fed. The DC24V coil must match your panel supply - a solenoid cannot be re-wired to a different voltage, so order the code that matches rather than adapting in the field. The flying-lead entry arrives as pre-wired tails, useful where a DIN socket connector is awkward to reach or you are terminating straight into a junction box.
A 1/8in port suits compact single-acting cylinders and light blow duties; step up within the family to a 1/4in or 3/8in code for a larger spring-return actuator. Because published flow figures for this family are not in our hands, send us the actuator size and duty and we will confirm sizing against the datasheet before you order. If you need a fully specified 3-port valve today, the AirTAC 3V2 and 3V3 bodies have published flow and coil-power figures and cover the same port range. If your actuator is double-acting, no 3/2 valve will drive it - you need a 5-port AirTAC 4V valve.
Confirm before you order
- ✓ Port size and thread (PT from stock; G / NPT to order)
- ✓ Initial state — NC or NO, ordered up front
- ✓ Coil voltage matches your controller output
- ✓ Electrical entry — DIN plug or flying lead
- ✓ Single valve, bare base, or complete assembly
- ✓ Single-acting duty, not double-acting
Installation & Wiring Notes
- check Use clean air filtered to 40µm or finer.
- check Match the coil voltage to your controller output.
- check Use the manual override to test before powering up.
- check Leave the exhaust port clear, or fit a silencer.
- check Wiring by qualified personnel, per AirTAC documentation.
AirTAC 3V210-06 Solenoid Valve, 3V200 Series (3V21006NOBI) FAQ
We do not publish figures for this family, so we will not guess at them. Ask us through the RFQ and we will read the pressure range, flow and coil power straight from the AirTAC datasheet for you. If you need published numbers in front of you right now, the AirTAC 3V2 and 3V3 bodies are the fully documented 3-port alternatives in the same port range.
Normally open (this SKU) feeds the outlet whenever power is off; normally closed does the opposite. Pick NO when a power failure should leave your line supplied. A 3/2 valve drives single-acting, spring-return cylinders and blow or pilot duties - it cannot drive a double-acting cylinder, which needs air to both sides and therefore a 5-port AirTAC 4V valve. Several of these valves can also share one 3V200M manifold base instead of individual plumbing.
