Ball Valve – KHD-FSB2D

With precision-machined fire safe lip and grahite sealing, these API 607, ISO 10497 Fire Safe approved ball valves offer increased safety for the most demanding applications.

Two-piece ball valves are among the most commonly used ball valves.
As the name implies, a two-piece ball valve consists of two pieces, one with an end connection and the body.
The second piece fits into the first, holds the trim in place, and houses the second end connection.

Flanged ball valves provide effective control of oil and gas operations.
Their characteristic feature is the flanged ends that are bolted to the oil and gas piping.

Fire safe ball valves are designed to minimize fugitive emissions and downstream leakage when exposed to high temperatures during fires.
They differ from other industrial ball valves by remaining operable, or at least failing in a predictable manner, when exposed to high temperatures.

KHD-FSB2D ball valve
ISO direct-mount

A direct mounting flange according to ISO 5211 is standard for these ball valves.
This feature allows an actuator to be mounted without the need for a mounting bracket and drive adapter.
This results in a significant cost reduction, a compact automated unit, and a higher level of safety for operators.
