When the valve is closed, flow is blocked from port 1 to port 2. However, if the pressure in port 2 is
higher than port 1, the valve will not be able to block the fluid and it will flow from port 2 to port 1.

Note 1) The orifice size is just as a reference guide. Check the flow rate characteristics (conversion Cv).
Note 2) The flow rate characteristics of this product have variations.
When the highly precise flow control is required according to the system to be used, select an orifice diameter 1.3 times larger than that shown
above and install a restrictor on the downstream side of the solenoid valve to make the adjustment.
Note 3) Weight of grommet type. Add 10 g for conduit type, 30 g for DIN terminal type, 60 g for conduit terminal type respectively.
Note 4) Refer to “Glossary of Terms” on page 65 for details on the maximum operating pressure differential and the maximum system pressure.

Valve Leakage Rate
Internal Leakage
Note 1) Leakage is the value at ambient temperature 20°C.
Note 2) For seal material/FKM, refer to “Other Options” on page 49 for the
selection.
Note 3) The amount of leakage is the value at a differential pressure of
0.01 MPa or more, and a temperature of 20°C.
