*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).

Precautions
- *Do not connect directly to the body via apparatus or use in applications which may adversely affect human life.
- *Confirm the specifications. Give careful consideration to the operating conditions including the application, fluid and environment. Only use within the operating ranges detailed in the SMC catalog.
- *Be sure to confirm the compatibility of the fluid used and the constituent materials of the product before use.
- *Allow sufficient space for performing maintenance and inspection.
- *Keep the supplied fluid pressure within the operating pressure range.
- *Use within the ambient operating temperature range. Make sure that no fluids or corrosive gases touch and adhere to the exterior surface of the product.
- *Take measures against static electricity as some fluids can cause static electricity.
- *As the solenoid valve allows air leakage, it cannot be used for applications such as holding pressure (including vacuums) within pressure vessels
- *Do not use as an emergency shutoff valve, etc. The solenoid valve is not designed for safety applications such as being used as a emergency shut off valve. If the valve is to be used in these types of system, other reliable safety assurance measures should be taken.
- *See the SMC catalog for information other than that detailed above.
- *Pictures are of representational models.
