Be sure to read before handling.
Design
Warning
●All models
1. The body material is A6063,the bellows is SUS316L, and other metal components of the
vacuum part are made of SUS304. The sealing material of the vacuum part is FKM as
standard, but this can be changed to other materials (refer to “How to Order”). Confirm
whether the fluid to be used is compatible with the materials before use.
Grease for vacuum is applied to the sliding part of the vacuum (Fluorine grease: Y-VAC2).
After confirming the type of material used, be sure to use compatible fluids.
2. Select materials for the pilot pressure piping and fittings whose heat resistance is suitable for
the applicable operating temperature.
●Models with auto switch
1.Keep the temperature of the switch below 60
o
C.
●With heater (thermistor)
1. When using a model with a heater, a mechanism to prevent overheating should be installed
2.If using gases that generate a large amount of deposits, it is recommended that the valve
body be heated to prevent deposits from sticking to the valve surfaces.
Selection
●All models
1.
When controlling valve responsiveness, take note of the size and length of piping, as well
as the flow rate characteristics of the actuating solenoid valve.
2.
Keep the pilot pressure within the specified range.
3.
Operate within the specified operating pressure range.
4.
Operate within the specified operating temperature range.
5.
Please note, when selecting a product without an auto switch(es) (excluding those with
built-in magnet), it is not possible to mount an auto switch(es) following receipt of the product
from an SMC factory.
Mounting
● All models
1.
In high humidity environments, keep the valve packed until the time of installation.
2.
For models with switches, secure the lead wires so that they have sufficient slack, without
any unreasonable force applied to them.
3.
Perform piping so that excessive force is not applied to the flange sections. When there is
vibration from heavy objects or attachments, etc., fix piping so that vibration will not apply
torque directly to the flange section.
4.
Vibration resistance allows for normal operation of up to 30 m/s
2
(45 to 250Hz), but
continuous vibration may cause a decline in durability.
Arrange piping to avoid excessive vibration or impacts.
●High temperature type (temperature specification / H0 H4 H5)
1.
In models with a heater (thermistor), take care not to damage the insulation components of
the lead wires and connector section.
2.
The set temperature for models with a heater should be established without any drafts or heat
insulation. It will change depending on conditions such as heat insulation measures and the
