Fire safe 2-piece flanged ball valve

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.

  • The locking device is ideal for applications where it is critical to keep the valve positions fixed without the risk of accidental operation. The metal piece fit accordingly to the opening on the actuator to lock on open and close position. In addition, padlock can be added with key to lock and secure the position.
