SECTION I.

SAFETY PRECAUTIONS

To avoid possible injury to personnel or damage to valve parts, WARNING and CAUTION notes must be strictly adhered to. Modifying this product, substituting nonfactory parts, or using maintenance procedures other than outlined could drastically affect performance, be hazardous to personnel and equipment, and may void existing warranties.

1. WARNING: Standard industry safety practices must be adhered to when working on this, or any other, process control product. Specifically, personal protective and lifting devices must be used as warranted.

2. Depressurize and bleed the line on both sides of the valve before attempting to service the valve.

3. Check nameplate before installation to ensure that the valve is not installed in systems where service conditions exceed those for which the valve was designed.

B16.34 and pressures up to 1440 psi. Based on simplicity, the design allows easy plug removal and replacement, minimizing the number of spare parts and inventory required.

IMPORTANT NOTES ABOUT YOUR WARRANTY AND SAFETY

Replacement Parts

The use of parts and components other than those supplied by Flowserve Corporation could severely restrict the operation and performance of this valve. Unauthorized modifications or substitution of components can lead to valve failure due to corrosion and/or premature failure of the substituted parts.

Selection, Installation, Operation and Maintenance

Flowserve Corporation has established industry leader-ship in the design and manufacture of its products. When properly selected, each product is designed to perform its intended function safely during its useful service life. However, it is necessary that Flowserve’s customers be fully aware of their responsibilities when using these products.

Each Flowserve product may be used in numerous applications under a wide variety of industrial service conditions. Although Flowserve can, and

often does, provide general guidelines, it is obviously not possible to provide application specific data and warnings for all conceivable applications. The purchaser/end user must therefore assume the ultimate responsibility for the proper selection, installation, operation and maintenance of the products. Read the appropriate IOM before installing, operating or repairing any valve. The purchaser/end user should train its employees and/or contractors in the safe use of the Flowserve products in connection with the purchaser’s manufacturing processes.

Flowserve will continue to provide its customers with the best possible products and service available. We do not recommend substituting surplus or remanufactured valves over new Flowserve valves or those repaired in an authorized service center. Should you have any questions about these provisions or about Flowserve’s products in general, please contact your local Flowserve representative, who will be happy to help.

Paying close attention to safety is always extremely important. However, there are often situations that require special attention. These situations are indicated throughout this book by the following symbols:

DANGER – Immediate hazards which WILL result in severe personal injury or death.

NOTE: ALWAYS COORDINATE REPAIR ACTIVITY WITH OPERATIONS PERSONNEL, AND

FOLLOW ALL PLANT SAFETY REQUIREMENTS AND OSHA REGULATIONS.

WARNING – Hazards or unsafe practices which COULD result in severe personal injury or death.

CAUTION – Hazards or unsafe practices which COULD result in minor personal injury or product or property damage.
