Continuous energisation of the

have an adverse effect on the solenoid valve performance and the
peripheral equipment due to temperature rises caused by the heat
generation of the coil. Consult with SMC if valves will be continuously
energised for extended periods of time, or if the energised period per
day will be longer than the de-energised period. Use either DC
specification or power saving type.
When solenoid valves are mounted in a control panel, take measures
against radiation in order to keep the valve temperature within the
specified range. Use special caution when three or more stations
sequentially aligned on the manifold are continuously energised since
this will cause a drastic temperature rise.

Warning
Without an electric signal for the solenoid valve the manual override is
used for switching the main valve.
When the manual override is operated, connected equipment will be
actuated. Confirm safety before operating.

Caution
When locking the manual override on the push-turn locking types (D or E
