Limitations
The correct selection of materials of construction, seats and seals, internal valve components and pressure/
temperature ratings determines the safe use of the valves and the particular performance requirements for
the application. This information can be found on the name plate welded to the valve body. The combined
corrosion and erosion allowance for the valve body wall thickness is 1(mm). When this allowance has gone,
the valve should no longer be used. Inspect the valve wall thickness every time the valve is maintained. Refer
to Habonim Corrosion Data Chart T-614 to determine the corrosion rate for your application.
As the variety of applications these valves can be used in is large, it is impossible to cover all installation
and maintenance instructions for servicing the valves. It is the owner’s responsibility to use the valves as
recommended and in accordance with the pressure and temperature limits as stated in this manual. Where
in doubt, please consult with Habonim.
Any unstable fluid or gas should be identified by its manufacturer and must not be used with Habonim
valves.

Storage
Prior to storage, inspect the valve for shipping damage. Keep all protective packaging, flange covers and
end caps attached to the valves during storage. It is recommended to keep the valves in a clean and dry
environment until it is ready for use.
Carbon Steel valves have a “black oxide” and oil dipped finish. This nontoxic process is performed to retard
rusting during storage. It is not a substitute for paint or other means of protective coating to be applied to
the valve once installed.
Stainless steel valves have their natural finish and do not need any additional protection once installed.
4.1.
Long Term Storage
4.1.1.
It is advisable to store the valves in waterproof conditions. Ball valves should be protected to
safeguard against humidity, Moisture, dust, dirt, sand, mud, salt spray, and sea water.
4.1.2.
Manual ball valves must remain in the open position during the period of storage.
4.1.3.
Actuated valves (fail to close position) remain in closed position during this time.
4.1.4.
Valves may be stored as shipped, provided the above storage location and equipment orientation
instructions are followed
4.1.5.
In order to prevent damage, protective covers on valve ends should not be removed until
immediately prior to installation.
4.1.6.
Visual inspection should be performed on a semi-annual basis and results recorded.
