Precautions 2
Design
Warning
●All models
1. The body material is A6063, the bellows is SUS316L, and other metal seal material is SUS304.
Refer to Chapter 5, "Construction and Dimensions" (P. 11) for details.
Standard seal material in the vacuum section is FKM that can be changed to the other
materials. (Refer to Chapter 3, "Product Specific Precautions 3" (P. 7 to 8) for details.)
After confirming the type of material used, be sure to use compatible fluids.
2. Select materials for the actuation pressure piping and heat resistant fittings that are suitable
for the applicable operating temperatures.
●Models with auto switch
1. Keep the temperature of the switch below 60
●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
Caution
●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
Caution
● 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 30m/s
Be advised that continuous vibration may cause a decline in durability.
Arrange piping to avoid excessive vibration or impacts.
Be sure to read before handling.
