*1: Select an appropriate material for the wetted parts according to the type of fluid to be used. Be sure to check the chemical resistance beforehand.
*2: Indicates pressures which do not cause breakage or cracks after a 1 minute airtight test.
*3: Indicates the volume of the clearance inside the volume chamber after the volume of the diaphragm has been subtracted.
*4: As the body (orifice shape) is designed to eliminate residual liquid, mounting in a vertical orientation with the coil facing upward is recommended. If liquid pooling is not an issue, it may be installed in any orientation.
*5: If response speed is considered critical, take adequate regulations to prevent voltage fluctuations on the negative side.
*6: This value is depending on the measurement conditions and the sound level may change depending on the measurement conditions.
*7: See the SMC catalog if the valve is to be energized continuously for extended periods of time.
*8: According to JIS B8419:2010
{Value at an ambient and fluid temperature of 25°C, at rated voltage, at the maximum operating pressure (air) and when the N.C. (IN) port is pressurized}
The response time may vary depending on the supply pressure, fluid quality, piping conditions, ambient temperature, etc.
*9: Note that when the diaphragm material is Kalrez, the valve changeover time becomes significantly longer at ambient and fluid temperatures of 15°C or less in comparison to at room temperature (roughly 25°C).
*Kv, Cv values conform to JIS B 2005:1995. C and b values conform to JIB B8390:2000.
