DEV BALL SERIES

FORGED
BALL VALVE

Ball valves are mainly used to quickly shut off or open fluid flow; quarter-turn operation makes them ideal for on-off service. They also offer low pressure loss when fully open, simple construction, and relatively easy maintenance, so they are widely used in industrial piping.

BALL VALVES

Conforms to API 800/1500 and ASME Class 150-2500 with sizes from 3/8" to 2". Offers socket-weld, threaded, butt-weld, and flanged ends. Main features include bolted or welded bonnets, OS&Y design, solid wedge disc, and renewable seats. Manufactured in carbon steel, stainless steel, and special alloys such as A182-F5, A182-F304, and A350-LF2 for durable multipurpose service.
