WARNING:
Warns against an unsafe situation or practice that, if not avoided, could result in damage or injury.
1. GENERAL SAFETY
At all times, personal safety equipment, safety glasses, safety boots with crush-resistant toe caps, hard hat, gloves should be worn for
pinch protection and while handling valves exposed to chemicals.
2. GENERAL INFORMATION
The selection of the valve design and materials of construction as related to the specific service application is the sole responsibility
of the end user. All FNW BFV have an identification mark (casting or information tag) casted or attached on valve body. Important
information, including valve size, class, materials of construction and pressure ratings, are shown. Before installing, review corrosive
effects of the media to be used in the valve and assure it is compatible with the valve materials of construction. Do not install the valve
where the pressure/temperature ratings can be exceeded. Valve should be regularly maintained as mentioned in Maintenance section.
Valves used in services where erosion or other detrimental situations can occur should be inspected on a regular basis.
3. TRANSPORTATION
•
Valve weight over 20kgs should be transported using equipment or a machine, not manpower alone. Please refer to product catalogue
for details of valve unit weight.
•
Protect the valve sufficiently before transportation to avoid damage. Damage may cause leakage or corrosion.
•
Use containers for ocean transport. Use a covered vehicle for inland transportation to avoid exposure to wind and rain. If an uncovered
vehicle is used, cover the product with a protective waterproof cover.
•
Do not throw the product and do not apply a heavy load.
•
The valves should be secured during transport from shifting or falling and stored without heavy loads on top to avoid damage,
especially to the valve seat and disc.
