Cast Steel / Stainless Steel Ball Valve

A ball valve is a valve that opens by turning a handle, gearbox or other actuation methods attached to a ball inside the valve. The ball has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve and flow is blocked. The handle or lever will be in line with the port position letting you "see" the valve's position, position indicators will be applied to gearbox or actuators when required. Ball valves are durable and usually work to achieve perfect shutoff even after years of disuse. There are two type of ball valve based on the ball type, floating ball valve and trunnion mounted ball valve. Depends on the bore size, ball valve is separated into full port ball valve and reduced port ball valve. There are three types of body styles of Ball Valve: One-piece, Two piece split, Three piece split, top entry and welded, ball valves are available in two piece split, three piece split and welded.

Advantages of using Ball Valves:

•Quick quarter turn on-off operation •Tight sealing with low torque •Smaller in size than most other Valves

Ball Valves are manufactured in different body configurations

and the most common are:

•Top entry Ball Valves allow access to Valve internals for

maintenance by removal of the Valve Bonnet-cover. It is not

required to be removed Valve from the pipe system.

•Split body Ball Valves consists of a two parts, where one part

is smaller as the other. The ball is inserted in the larger body

part, and the smaller body part is assembled by a bolted

connection.

•The Valve ends are available as butt welding, socket welding,

flanged, threaded and others.
