
1: Please refer to the chart of measurement range of ethylene glycol aqueous solution on page 32 . Measurement is possible as long as
the fluid does not corrode the wetted parts, and viscosity is 3 mPa

s(3 cP) or less. Be aware that water leakage may happen due to
internal seal shrinkage or swelling depending on kinds of fluid. Refer to the "Applicable fluid list" on page 31 .

2: The operating pressure range and proof pressure vary depending on the fluid temperature. Refer to the chart on page 35 .

3: The response time is when the set value is 90% in relation to the step input. (The value will be 7 s for the temperature sensor output.)

4: When the temperature sensor is used, it will be 250 VAC.

5: 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.
