1: When the flow range of 40 (rated flow range: 5 to 40 L/min) is selected in the supply/return unit, it is possible to mount 5 stations at a
maximum.

2: Please refer to the chart of measurement range of ethylene glycol aqueous solution on page 50 . Measurement is possible as long as
the fluid does not corrode the wetted parts, and viscosity is 3mPa

s (3 cP) or less. Be aware that water leakage may happen due to
internal seal shrinkage or swelling depending on kinds of fluid.

3: The operating pressure range and proof pressure vary depending on the fluid temperature. Refer to the chart on page 59 .

4: If a reduced piping diameter or the piping layout cause a restriction, it may not satisfy the specifications.

:

The form of the G thread (including the major and minor diameter and pitch of the internal thread) is based on JIS B0202 (ISO228-1).

Products indicated as ISO1179-1 (G thread for hydraulics) or ISO16030 (G thread for pneumatics) are based on JIS B0202
(ISO228-1) for effective depth of thread, seat surface area, surface roughness and squareness.

For ISO1179-1 (G thread for hydraulics), the withstand pressure is specified for each product. SMC do not guarantee the withstand
pressure specified in ISO1179-1, ISO1179-2, ISO1179-3, or ISO1179-4.

For ISO16030 (G thread for pneumatics), the withstand pressure is specified for each product. SMC do not guarantee the withstand
pressure specified in ISO16030.

5: Any products with tiny scratches, smears, or display colour variation or brightness which does not affect the performance are verified
as conforming products.
