How to Order (Solenoid Valve for Manifold)
Mounting orientation exists
when mounting valves onto
manifold base. Refer to page
76 for details.
Caution
∗1 For connection,
prepare a fitting
compliant with
ISO 16030 and
JIS B 8674.
5 x Rc1/4
(Individual port)
Enter the product’s part number in order, counting the 1st station from the D side
(left in the manifold arrangement, when viewing the individual port in front).
Enter the valve and blanking plate to be mounted under the manifold
base part number.
<Example>
VVX214B05……......1
∗VX2A4AA ………….4
∗VVX021S-4A-F ……1
“∗” is the symbol for mounting.
Add an “∗” in front of the part numbers for solenoid
valves etc. to be mounted.

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.
