Transmitter Isolation Valve – C132 Fabri-Valve®

The Fabri-Valve C132 transmitter isolation valve is designed specifically to isolate an instrument transmitter from a tank. This allows transmitter replacement or maintenance of the transmitter without disrupting the process or draining the vessel. A special tank side flange permits blind boltup from the tank exterior. This is accomplished by moving the upper flange holes outboard. They remain on the ANSI 125/150 bolt circle but are now located closer to the horizontal centerline. Fabri-Valve transmitter isolation valves are designed to fit installations where the upper tank flange bolts are located 25° to 27° above the horizontal centerline. The transmitter side flange bolting is a standard ANSI 125/150 configuration.
