Precautions 1
Be sure to read before handling.
Design
Warning
●All models
1.
The body material is A6063, the bellows is SUS316L, and other metal seal material is SUS304.
Standard seal material in the vacuum section is FKM that can be changed to the other materials
(please refer “How to Order”). Use fluids those are compatible with using materials after
confirming.
2.
Select materials for the actuation pressure piping, and heat resistance for fittings that are
suitable for the applicable operating temperatures.
●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
heating of other piping. Fine adjustment is not possible.
3.
When installing heater accessories or mounting a heater, check insulation resistance at the
actual operating temperature. A current leakage breaker or fuse should be installed.
