CAUTION:
• Valve pressure ratings are based on many variables,
including valve series and size, as well as body, seat and
bolt material. Verify that the application does not exceed
the pressure or temperature rating of the valves.
• Always depressurize the line with the valve in the open
position before disassembly.
• Wear protective equipment and take appropriate
precautions to safeguard against injury caused by the
discharge of trapped fluids.
• Use only FNW recommended spare parts for maintenance.
• To ensure safety and to maintain warranty, never modify
the valve in any way without prior approval from FNW.
We reserve the right to modify or improve the designs or
