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.

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.
