About the AirTAC 2V250-20
The AirTAC 2V250-20 is a normally closed 2/2-way solenoid valve for air, water and oil, with PT3/4 ports and a Ø25.0 mm orifice (Cv 13.00). It is a diaphragm valve with an internal pilot: the line pressure helps open it, giving a large flow from a small coil, so it needs at least 0.05 MPa across the valve. The body is brass with NBR seals.
It works at 0.05 – 1.0 MPa with media up to 20 cSt viscosity, proof pressure 1.5 MPa, and responds in 0.05 s or less. The coil draws 7.0 VA (AC) or 7.0 W (DC), class B insulation.

Where the 2V250-20 Is Used
Water lines
Switches water supplies for cooling, washing and rinsing.
Air and gas shut-off
Opens and closes compressed air or inert gas lines.
Light oil
Handles oils up to 20 cSt, such as ISO VG32 hydraulic oil.
Choosing the Right 2V250-20 Configuration
Choose the coil voltage to match your control circuit: DC24V (B), AC220V (A), AC110V (C), AC24V (E), DC12V (F). Supply tolerance is AC ±15% and DC ±10%.
For the electrical entry, the standard DIN connector takes your own cable; the I version has a 0.5 m lead wire already attached.
The port thread: PT is standard, G (BSPP) is marked G.
The 2V is normally closed: the valve opens only while the coil is energised.
Pilot-operated sizes need at least 0.05 MPa pressure difference to open; for lines that may run at zero pressure, use the direct-acting 2V025.
AirTAC 2V250-20 FAQ
Normally closed: the valve opens only while the coil is energised.
Air, water and oil up to 20 cSt. Flammable media such as ethylene glycol need an explosion-proof coil, and acetone is not suitable for NBR seals; for media not in the catalog fluid table, check with us first.
0.05 – 1.0 MPa (7 – 145 psi), proof pressure 1.5 MPa. As a pilot-operated valve it needs at least 0.05 MPa to open.
DC24V (B), AC220V (A), AC110V (C), AC24V (E), DC12V (F). The letter after the port size gives the voltage.
