Precautions for 3 Port Solenoid Valve 2
Be sure to read before handling.
Design / Selection
4. Surge voltage intrusion
With non-polar type solenoid valves, at times of sudden
interruption of the loading power supply, such as emergency
shutdown, surge voltage intrusion may be generated from
loading equipment with a large capacity (power consumption),
and a solenoid valve in a de-energized state may switch over
(see Figure 1).
When installing a breaker circuit for the loading power supply,
consider using a solenoid valve with polarity (with polarity
protection diode), or install a surge absorption diode between
the loading equipment COM line and the output equipment
COM line (see Figure 2).
5. Operation in low temperature conditions
It is possible to operate a valve in extreme temperatures, as
low as –10°C. Take appropriate measures to avoid the
freezing of drainage, moisture, etc., in low temperatures.
6. In case of extremely low differential pressure
between the inlet side and the outlet side.
(0.001 MPa or less as a guide).
Note that air may not be output or the flow rate may
deteriorate excessively due to the quality of the lubricant and
air in the solenoid valve (mixing in of the drain, etc.).
7. Mounting orientation
Refer to the specifications of each series.
Please consult with SMC for models not indicated in the
specification column.
1. Operation manual
Install the products and operate them only after reading the
operation manual carefully and understanding its contents.
Also, keep the manual where it can be referred to as
necessary.
2. Ensure sufficient space for maintenance activities.
When installing the products, allow access for maintenance
and inspection.
3. Tighten threads with the proper tightening torque.
When installing the products, follow the listed torque
specifications.
4. If air leakage increases or equipment does
not operate properly, stop operation.
Check mounting conditions when air and power supplies are
connected. Initial function and leakage tests should be
performed after installation.
5. Painting and coating
Warnings or specifications printed on or affixed to the product
should not be erased, removed, or covered up.
Please consult with SMC before applying paint to resinous
parts, as this may have an adverse effect due to the solvent
in the paint.
