Airtac 3V2 Solenoid Valve 3V208NCC
The AirTAC Airtac 3V2 Solenoid Valve 3V208NCC is a genuine 3-port 2-position (3/2) solenoid valve with 1/4 in ports. It either feeds its outlet or vents it to exhaust, which is what makes it the valve for single-acting cylinders, on/off air blow, clamping, vacuum switching and pilot duty.

About the Airtac 3V2 Solenoid Valve 3V208NCC
The AirTAC 3V208NCC is a 3/2-way solenoid valve in the normally closed (NC) configuration: its 1/4in PT outlet stays closed until the AC110V coil is energised, then the valve feeds the line and vents it back to exhaust when the coil drops. Because it is direct-acting with a spring return, it shifts reliably at 0 MPa and needs no minimum pilot pressure.
A coaxial poppet inside the body gives tight shut-off and a per-port flow of Cv 0.19 (3.4 mm2 effective area). The valve also carries a negative-pressure rating of -102.2 kPa to 0.1 MPa, so one valve type can serve both vacuum and pressure circuits on the same machine. A manual override is fitted to help installation and commissioning.

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 3V2 Solenoid Valve 3V208NCC Is Used
Vacuum sheet lifting on a CNC router
Switches vacuum to cup modules holding MDF sheets; the -102.2 kPa rating lets one valve handle both the vacuum draw and the pressure blow-off release.
Pneumatic clamp on an assembly fixture
Energise to clamp, de-energise to vent the single-acting clamp cylinder through the exhaust port - the spring return gives a fail-vented rest state.
Pilot stage for a large process valve
AC110V matches common control voltage; the NC state keeps the pilot line vented until deliberately triggered, and the manual override aids setup.
Is the Airtac 3V2 Solenoid Valve 3V208NCC the Right Part?
Choose this code when you need 1/4in PT ports, a normally closed start state, an AC110V coil and a DIN plug connection - all five points must match your drawing. If the duty is small and coil economy matters, the 3V1 series runs 3.0 W on DC24V instead of the 7 VA here; if you are ganging many stations and can trade flow, the base-mounted 3V2M (Cv 0.1) saves space through a manifold. When Cv 0.19 is simply not enough, step up to the 3V3 on 1/4in ports with Cv 0.62, which is also vacuum-rated.
Need to drive a double-acting cylinder? A 3/2 valve cannot - that requires 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 Stay within 0-0.8 MPa (0-114 psi) operating pressure.
- 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 3V2 Solenoid Valve 3V208NCC FAQ
Port: 1/4in PT, effective area 3.4 mm2 per port, Cv 0.19 (the 1/8in 3V206 gives 3.2 mm2 / Cv 0.18). Operating pressure 0-0.8 MPa; the body is also vacuum-rated from -102.2 kPa to 0.1 MPa. Temperature range -20 to 70 C. Coil: AC110V here, 7 VA for AC types and 7.0 W for DC types. Protection IP65 (DIN 40050).
No. A 3/2 valve has three ports and two states, so it either feeds a single line or vents it - correct for single-acting spring-return cylinders, blow-off, clamps and pilot duty. A double-acting cylinder needs supply and exhaust on both sides, which is the job of a 5-port valve such as the AirTAC 4V series.
