The majority of this information is common knowledge for valve users, where the information applies to all the standard valves. When the VTI product is installed in applications for which they are designed will give hassle free service.
The end user is responsible for ordering the correct valves. VTI valves are to be installed in the observance of the pressure rating and design temperature. Prior to installation, the valves and nameplates should be checked for proper identification to be sure the valve is of the proper type, material, and is of a suitable pressure class and temperature limit to satisfy the application requirements.
Do not use any valve in applications where either the pressure or temperature is higher than the allowable working values. Also valves should not be used in service media if not compatible with the valve material of construction, as this will cause chemical attacks.
Valves should be inspected upon receipt to determine:
- Compliance to purchase order requirements.
- Correct type, pressure class, size, body and trim materials and end connections (this information may be found on the nameplate or may be stamped on the body of the valve).
- Any damage caused during shipping and handling to end connections, handwheel or stem.
The End User is advised that misapplication of the product may result in injuries or property damage. A selection consistent with the particular performance requirements is important for proper application.
Always follow safety procedures when working on a valve.
