These safety instructions are intended to prevent hazardous situations and/or equipment damage. These instructions indicate the level of potential hazard with the labels of “Caution,” “Warning” or “Danger.” They are all important notes for safety and must be followed in addition to International Standards (ISO/IEC)*1), and other safety regulations.

*1) ISO 4414: Pneumatic fluid power -- General rules relating to systems

ISO 4413: Hydraulic fluid power -- General rules relating to systems IEC 60204-1: Safety of machinery -- Electrical equipment of machines (Part 1: General requirements) ISO 10218-1992: Manipulating industrial robots -- Safety

Caution

Warning

Danger

Caution indicates a hazard with a low level of risk which, if not avoided, could result

in minor or moderate injury.

Warning indicates a hazard with a medium level of risk which, if not avoided, could result in death or serious injury.

Danger indicates a hazard with a high level of risk which, if not avoided, will result in death or serious injury

Warning

1. The compatibility of the product is the responsibility of the person who designs the

equipment or decides its specifications.

Since the product specified here is used under various operating conditions, its compatibility with specific equipment must be decided by the person who designs the equipment or decides its specifications based on necessary analysis and test results. The expected performance and safety assurance of the equipment will be the responsibility of the person who has determined its compatibility with the product. This person should also continuously review all specifications of the product referring to its latest catalog information, with a view to giving due consideration to any possibility of equipment failure when configuring the equipment.

2. Only personnel with appropriate training should operate machinery and equipment.

The product specified here may become unsafe if handled incorrectly. The assembly, operation and maintenance of machines or equipment including our products must be performed by an operator who is appropriately trained and experienced.

3. Do not service or attempt to remove product and machinery/equipment until safety is

confirmed.

1.The inspection and maintenance of machinery/equipment should only be performed after measures to

prevent falling or runaway of the driven objects have been confirmed.

2.When the product is to be removed, confirm that the safety measures as mentioned above are implemented and the power from any appropriate source is cut, and read and understand the specific product precautions of all relevant products carefully.

3.Before machinery/equipment is restarted, take measures to prevent unexpected operation and malfunction.

4. Contact SMC beforehand and take special consideration of safety measures if the product is

to be used in any of the following conditions.

1. Conditions and environments outside of the given specifications, or use outdoors or in a place exposed to direct sunlight.

2. Installation on equipment in conjunction with atomic energy, railways, air navigation, space, shipping,

vehicles, military, medical treatment, combustion and recreation, or equipment in contact with food and beverages, emergency stop circuits, clutch and brake circuits in press applications, safety equipment or other applications unsuitable for the standard specifications described in the product catalog.

3. An application which could have negative effects on people, property, or animals requiring special safety analysis.

4. Use in an interlock circuit, which requires the provision of double interlock for possible failure by using a

mechanical protective function, and periodical checks to confirm proper operation.

1. Product Specific Precautions 1

Common Specific Precautions 1

Precautions on Design

Warning

●All models

1. The body material is SCS13, 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. Grease for vacuum is applied to the sliding part of the vacuum (Fluorine grease: Y-VAC2).

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. The switch section should be kept at the temperature no greater than 60 oC

Selection

Caution

●All models

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.

Actuating pressure should be kept within the specified range.

0.4 MPa to 0.5 MPa is recommended.

Use within the limits of the operating pressure range.

●High temperature type

In the case of gases which cause a large amount of deposits, heat the valve body to prevent deposits in the valve.

Be sure to read before handling.

Mounting

Caution

● All models

In high humidity environments, keep the valve packed until the time of installation.

In case with switches, secure the lead wires so that they have sufficient slack, without any unreasonable force applied to them.

Perform piping so that excessive force is not applied to the flange sections. In case there is vibration of heavy objects or attachments, secure them so that torque is not applied directly to the flanges.

Vibration resistance allows for normal operation of up to 30 m/s2 (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)

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

Piping

Caution

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

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.

Maintenance

Warning

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).

Caution

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

2. Replace the bonnet assembly and the O-ring when the end of its service life is approached. *For details regarding endurance cycles, please reference Section 7 of this Operation manual titled Period and scope of warranty . (pages 11)

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 Section 8 Parts Replacement Procedure (pages 12 to 15) for details.)
