Product Summary

Isolating ball valve is a valve with a spherical disc that is isolated, the part of the valve which controls the flow through it. The sphere 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 inline with the port position letting you "see" the valve's position. The ball valve, along with the butterfly valve and plug valve, are part of the family of quarter turn valves.

Isolating ball valves were initially intended for use in aircraft fuel systems, where weight and space are at a premium. They consist of a body which houses a rotating ball which has an orifice or bore machined directly through it. The ball is located in the body by two sealing rings. Rotation of the ball through 90° opens and closes the valve and allows fluid to flow directly through the orifice. In the closed position, the blank sides of the ball block the inlet and the outlet preventing any flow. There are two basic designs of ball valves - the floating ball design, which relies on the valve seats to support the ball, and the trunnion mounted ball, which uses a trunnion to support the ball. Trunnion mounting is used on larger valves, as it can reduce the operating torque to about two-thirds of that provided by a floating ball.

Isolating ball valves are commonly used in gas and oil pipelines, it is essential that the valves used in such applications are firesafe. A valve is considered firesafe if, when exposed to fire conditions, it will continue to provide minimal leakage through the seat and stem, and provide effective shut-off during or following a fire or exposure to excessive temperatures. Standards relating to fire-safety are set out in BS 6755 and API RP 6FA.
