Fisher FB and FBG Control ValvesFisher FB and FBG fabricated angle and globevalves are used with compressible fluids on specialapplications requiring maximum noise attenuationcapability and high capacity. Typical applicationsinclude main steam reducing valves and compressorbypass valves. FB and FBG valves are alsocommonly used for sour gas applications inpetrochemical and gas processing plants.
Features
Noise AttenuationWhisper Trim III orWhisperFlo cages used in FBD, FBGT, or FBT(figure 1) valves can reduce noise produced by highflow rates and large pressure drops.
Minimal Noise RegenerationRegenerationof valve noise is significantly reduced by reducingthe outlet flow velocity with an expanded-outletdesign.
Hung Cage DesignThe design eliminatesgasketing problems caused by thermal expansionand contraction of long parts such as the cageassembly.
Excellent Sealing CapabilityTheENVIRO-SEAL or HIGH-SEAL packing systemoptions are available. These packing systemsprovide excellent sealing, guiding, and loading forcetransmission.
Tight ShutoffA springloaded seal ring withPEEK antiextrusion rings is available on FBTvalves for class V shutoff up to 316C (600F). Boreseal is available on FBD valves for class V shutoffabove 316C (600F).
