Three-piece design
|
|
Ball Valves featuring this design are the most easily on-line maintainable in
their class. By removing three body connector bolts and loosening the fourth,
the body can be swung away using the fourth bolt as the fulcrum, to carry out
any installation or maintenance operation on the valve. This feature reduces
maintenance downtime to a bare minimum.

Single-piece / Two-piece design
|
|
Single-piece ball valves are high performance valves, which come with a
one-piece integrally flanged body, in sizes of up to 200mm reduced bore and
40mm full bore. This design offers the unique advantage of eliminating the
possibility of external leakage to the atmosphere through bolted body joints.
These environment-friendly and high-integrity valves are preferred in critical
applications where the media is expensive, volatile or toxic, and where
external leakage or wastage is unacceptable. The two-piece design
complements the single-piece design in sizes of 250mm and above reduced
bore, and 50mm and above full bore.
