*1: Orifice sizes are for reference. Check the flow rate characteristics (conversion Cv).
*2: There are variations in the flow rate characteristics of the product.
If high precision flow rate control is needed for the system, adjust accordingly by selecting an orifice that is at least 1.3 times larger in diameter and use a diaphragm, etc., on the secondary side of the solenoid valve.
*3: This is the grommet value. Add 10 g for conduit types, 30 g for DIN terminals, 60 g for conduit terminals respectively.
*4: See the glossary for details on the maximum operating pressure differential and the maximum system pressure.

Fluid Temperature and Ambient Temperature

Fluid temperature: -10 to +60°C *: Dew point temperature: -10°C or less
Ambient temperature: -20 to +60°C

Valve Leakage Rate

Internal Leakage

Seal material^*2	Leakage Rate (Air)^*1
NBR (FKM)	1 cm³/min or less (aluminum body type)
NBR (FKM)	15 cm³/min or less (resin body type)

Exterior Leakage

Seal material^*2	Leakage Rate (Air)^*1
NBR (FKM)	1 cm³/min or less (aluminum body type)
NBR (FKM)	15 cm³/min or less (resin body type)

*1: The leakage rate is at an ambient temperature of 20°C.
*2: See the special options in the catalog for FKM sealing material.
*3: The leakage amount is at 20°C and with a differential pressure of 0.01 MPa or more. Contact the SMC support center when the differential pressure is less than 0.01 MPa.

*Refer to the SMC catalog for other part numbers.
