1. Product Specific Precautions 1

Common 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.

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.

●With heater (thermister)

1.When using a model with a heater, a mechanism to prevent overheating should be

installed.

Selection

●High temperature type

1. If using gases that cause alarge 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. 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.

3. Vibration resistance allows for normal operation of up to 30m/s2(45 to 250Hz).

Be advised that continuous vibration may cause a decline in durability.

Arrange piping to avoid excessive vibration or impacts.

●High temperature type (temperature specification /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.

4. When a valve is to be heated, only the body section should be heated, excluding the handle

section.

5. In models with a heater, when the heater is in operation, the entire valve becomes hot. Be

careful not to touch it with bare hands, as burns will result.

6. The heater temperature will initially decrease several % after the heating starts and then

gradually becomes stable. (The heater temperature may decrease approximately 5 to 10%

due to individual differences.)

Caution

XL*****-OMJ0005-C

1. Before mounting, clean the surface of the flange seal and the O-ring with ethanol, etc.

2. There is an indentation of 0.1 to 0.2mm in order to protect the flange seal surface, and it

should be handled so that the seal surface is not damaged in any way.

If the fluid or reaction product (deposit) may cause the valve to become unsafe, the valve

should be disassembled, cleaned and re-assembled by an operator who has sufficient

knowledge and experience (e.g. a specialist).

1.When removing deposits from the valve, take care not to damage any part of it.

2.Replace the handle assembly when the valve is approaching the end of its service life.

*For the endurance cycles, refer to Chapter 5, “Period and Scope of Warranty” (P. 9).

3.If damage is suspected prior to the end of the service life, perform early maintenance.

4.SMC specified parts should be used for service. Refer to the Construction / Maintenance

parts table.

5.When removing the valve seal and external seal, take care not to damage the sealing

surfaces. When installing the valve seal and external seal, be sure that the O-ring is not

twisted. (Refer to Chapter 6, “Parts Replacement Procedure” (P. 10 to 11) for details.)

The heaters are PTC thermistor type design.

These thermistors self regulate their temperature

by switching the resistance at certain critical

temperatures, so a separate temperature

controller is unnecessary.

If the temperature of the PTC heaters fitted exceeds

200oC, then it may fail. The maximum operating

temperature for the valve is 150oC. If the heater

temperature is over 200oC or valve temperature is

over 150oC, please use thermostat to control the

heaters to prevent overheating.

With PTC type heaters, there is an initial surge of current (inrush current) after the power is supplied.

These inrush current will reduce overtime. If multiple heater assemblies are used, the inrush current to

the heaters will be magnified and care should be taken. When multiple heater assemblies or valves

are used, do not apply power to the heater assemblies simultaneously. Keep approximately 30

seconds between applications of power to each heater assembly. This will allow for incremental

spacing to prevent harmful large initial surge.
