Three-piece design 
Standard seriesThis 3-piece Ball Valve
is the most easily on-line maintainable in its 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, thus reducing downtime. This
valve can be offered in a wide variety of body and seat combinations.Three-piece

Fire-safe seriesThis 3-piece fire-safe design Ball Valve
features a secondary metal seat, which renders the valve fire-safe. When
the seat is totally sublimated in a fire, the ball moves and rests
against the lip, forming a metal to-metal seat, thus ensuring
leak-tightness.Single-piece / Two-piece design
Fire-safe series (Class 150 & Class 300)These
high performance full bore ball valves come in single-piece design (in
sizes of 15-40mm) as well as in two-piece design (in sizes of 50-200mm).
Advanced features such as fire safety, antistatic capability, cavity
relief and blow-out proof stem are built into these valves. They are
supplied with an integral actuator-mounting flange with drilled and
tapped holes conforming to ISO 5211.
