Fig.652 Installation & Maintenance Manual
General Information:
•
To provide an optimum service life, the valve should be operated only in its fully
open or fully close position. If the valve is used in partly open (throttled)
position, seat life may be reduced.
•
Extending the handle lever is considered misuse and can damage the valve or
cause injuries.
•
The valve body rating can be higher than the seat rating.
•
High viscous or abrasive media, frequent operation and temperature
fluctuations could cause an increase in valve torque.
•
Valve pressure varies under different models, sizes, working temperatures and
materials. Please verify the application within the limits specified herein and as
described on metal plate spot welded on valve body. References contained in
this documents to the 'PED" are in regards to European Pressure Equipment
Directive 97/23 EC.
•
Always use Trueline recommended spare parts for maintenance and
replacement.
Shipping and Storage:
All valves are packed in strong cardboards and plastic bags to avoid any possible
damage during transportation. All the valves must be examined on reception, to ensure
that they have not suffered any damages during transport, and the supplier must be
informed of any damages observed. If the items are not for immediate use, please
follow the following instructions:
1. Leave the valves in fully open position. Never leave the valve in a partially open
position.
2. Always keep the protective covers in place until the valve is ready for
installation.
3. The valves should not be unpacked until they are to be definitively installed,
except for purpose of inspection. After inspection they will be packed again.
4. The valves should be stored under cover and protected from severe weather
conditions and foreign bodies.
5. Stainless steel ball valves do not need any additional protection coatings once
they are installed.
6. Valves to be stored for a long period of time should be inspected by QC
personnel every six months and every three months for automated valves.

- Page 3 Fig.652 Installation & Maintenance Manual Preventive Maintenance: Preventive maintenance operations essentially consist of periodic inspections to ensure that the valve is working properly. 1. The valve must be opened and closed at least once every six months. The user will be responsible for establishing opening and closing plans that are adequate for the working conditions and fluids used. 2. Before making the maintenance, always make sure the pressure is released and the line has been closed. 3. Wear protective clothing adequate for the circulating fluid. (Comply with the safety guidelines laid down by the company). 4. If leakage happens at the stem, tighten the stem nut a quarter turn as a routine ...
