Three-piece design
Standard series

This 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 design
Fire-safe series

This 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.

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.

These three-piece ball valves, fitted with special filled PTFE seats, are specially designed for on/off steam applications.

The full range of reduced and full-bore valves are available with special designs for steam services. In general, these valves will have seats of special filled PTFE and body seals of graphite. Pressure ratings will be as per flange ratings in flanged valves and 103kg/cm2 for screwed/socket-weld end valves.
