SMC IL220N02L (IL220-N02-L) - Lock-Up Valve, NPT1/4, 3-port

SMC IL220N02L Lock-Up Valve — 3-port, NPT1/4, low temperature. 3-port lock-up valve, IL200 series, low-temperature (L) option. Signal pressure max. 1.0 MPa; set pressure range 0.14 to 0.7 MPa (maintain 0.1 MPa or more differential between signal and set pressure); shut-off circuit pressure max. 0.7 MPa; lock differential 0.01 MPa; port size NPT1/4 (thread type N); low-temperature suffix L rated -30 to 60 degrees C; weight 0.7 kg. On loss of signal, switches supply from IN1 to IN2 for the OUT port.

IL220-N02-L Applications

The IL220-N02-L is a 3-port lock-up valve for air-operated process control lines with NPT1/4 piping and a low-temperature (-30 to 60 C) build. Unlike the shut-off IL201/IL211 types, the 3-port IL220 changes the supply port when a fault occurs: on loss of signal pressure it shuts IN1 and opens the flow path from IN2 to OUT, redirecting the actuator to an alternate air source. Used for fail-safe switching of pneumatic actuators and control valves in cold or outdoor installations.
