About the AirTAC 2KS150
The AirTAC 2KS150 is a normally open 2/2-way solenoid valve for air, water and oil, with 1/2" ports and a Ø15.0 mm orifice (Cv 5.50). It is internally piloted: the line pressure helps move the piston, which gives a large flow from a small coil, so it needs at least 0.05 MPa across the valve to switch. The valve is open with the coil off and closes while the coil is energised.
The body is SUS304 stainless steel with FKM (FPM-F) seals. It handles media up to 20 cSt, proof pressure 1.5 MPa. The coil is rated IP65 with class B insulation and comes with a DIN connector or a 0.5 m lead wire.

Where the 2KS150 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.
Choosing the Right 2KS150 Configuration
The port is 1/2"; PT is standard, G (BSPP) is marked G, NPT is marked T.
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 2KS is normally open: the valve is open with the coil off and closes while the coil is energised. For a normally closed valve use the 2S.
Pilot-operated sizes need at least 0.05 MPa pressure difference to switch; for lines that may run at zero pressure, use a direct-acting 2KS030 or 2KS050.
AirTAC 2KS150 FAQ
Normally open. The valve is open with the coil off and closes while the coil is energised.
Air, water and oil up to 20 cSt. Water +1 to +80 °C, air -20 to +90 °C (dew point -20 °C or lower), oil -10 to +80 °C, ambient -20 to +70 °C. For media not listed in the catalog, check with us first.
It works at a pressure difference of 0.05 – 0.7 MPa (10 – 100 psi); proof pressure 1.5 MPa. As a pilot-operated valve it needs at least 0.05 MPa to switch.
DC24V (B), AC220V (A), AC110V (C), AC24V (E), DC12V (F). The letter after the port size gives the voltage.
Orifices, pressure ratings and coils are the same; the 2KS has a SUS304 stainless steel body for corrosive surroundings, the 2KW a brass body. Pilot-operated 2KS valves also come in 320, 400 and 500 sizes; the 2KW stops at 250.
