1. Product Specific Precautions 1
Common Precautions 1
Be sure to read before handling.
Design
Warning
●All models
1.
The material of the body and bonnet is A6063, 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).
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.
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.
The specified range of XLG-16, XLG-25 and XLG-40 is from 0.3MPa to 0.5MPa, and that
is for XLG-50, XLG-63, XLG-80, XLG-100 and XLG-160 is from 0.4MPa to 0.5MPa.
3. Keep within the specified range of the pilot pressure.
●High temperature type
1.
If using gases that cause a large amount of deposits, heat the valve body to prevent deposits
in the valve.
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 insulationcomponents 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.
