Scope

One of the most trusted valves in the petroleum
industry, the CAMERON T31 Fully Welded Body Ball
Valve combines the strength of forged components
with a lightweight and compact spherical design.
CAMERON T31 Fully Welded Body Ball Valves
satisfy ASME 150 through 2500 (PN 20 through
PN 420) and API 2000 through 10000 standards.
Made of forged steel to assure uniform fine grain
structure and toughness, they may be specified
in sizes from 2" to 56" (DN 50 to DN 1400).

Storage

The valves are conditioned for a storage period of
approximately six months. The following care should
be taken when storing valves.
1. Make sure the valve end connection covers remain
in place during storage.
2. If the valve does not have an operator already
installed and the valve will be stored outside, the
open stem extension or the stem adapter should
be covered to avoid water buildup.
Installation, Operation and Maintenance Manual
E N G I N E E R E D V A L V E S
Engineered for heavy-duty
maintenance, the CAMERON T31 Fully Welded
Body Ball Valve is commonly selected for a
number of applications. The distinctive design of
the CAMERON T31 Fully Welded Body Ball Valve
gives it maximum strength and minimum weight
as well as maximum resistance both to pipeline
pressure and stresses. The compact, spherical
design also eliminates body flanges, thus reducing
overall size and leak paths.
Figure 2 - Typical Valve Nameplate.
3. If long-term storage is required, the valve
should be conditioned using a corrosion
inhibitor and end connection covers.
Follow the guidelines found in CAMERON
Engineering Bulletin 476B for long term
storage.
