| 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. | | Type | Units | ASME Class | | 150 | 300 | 600 | | Reduced Bore | Inches | 1/2 - 10 | 1/2 - 10 | 1/2 - 2 | | mm | 15 - 250 | 15 - 250 | 15 - 50 | | | Materials of Construction
