Fisher FB, FBG Welded Angle and Straight Way Valves – Fisher are also commonly used in acid gas applications in petrochemical and natural gas processing plants.
Fisher FB, FBG Welded Angle and Straight Way Valves – Fisher have following features:
Noise Reduction — The Whisper Trimtmiii or Whisperflotm cage used in FBD, FBGT or FBT valves reduces noise generated by high flow rates and large pressure drops.
Small noise generation — Using an extended outlet design, the outlet flow rate is reduced, thus significantly reducing the generated valve noise.
Suspend cage design – This design reduces gasket sealing problems caused by expansion and contraction of long components such as cage assemblies.
Excellent SEAL performance — Enviro-SealTM and high-seal packing systems are available.These packing systems provide excellent sealing, steering and load transfer performance.
TIGHT SHUTOFF — Fisher FB, FBG Welded Angle and Straight Way Valves – Fisher are equipped with a spring-loaded seal ring with a PEEK escape ring for class V shutoff at up to 316°C (600°F).
