The Fisher™ FB Angle Valves are engineered for severe service applications involving compressible fluids where maximum noise reduction and high flow capacity are critical . These welded angle valves are ideal for demanding roles such as main steam pressure reduction and compressor bypass valves . They are also commonly employed in acid gas applications within petrochemical and natural gas processing plants .
The Fisher™ FB Angle Valves are engineered for severe service applications involving compressible fluids where maximum noise reduction and high flow capacity are critical . These welded angle valves are ideal for demanding roles such as main steam pressure reduction and compressor bypass valves . They are also commonly employed in acid gas applications within petrochemical and natural gas processing plants .
The FB valve design incorporates an expanded outlet that lowers outlet velocity, which significantly reduces generated noise . Its construction minimizes gasket sealing issues caused by the thermal expansion and contraction of long components, such as the cage stack . For enhanced performance, the valves are available with optional Whisper Trim™ III or WhisperFlo™ cages to effectively manage noise from high flow velocities and large pressure drops . Additionally, you can choose between the ENVIRO-SEAL™ or HIGH-SEAL packing systems, which offer excellent sealing, guiding, and load transmission capabilities .
Key Features & Benefits:
Advanced Noise Abatement: Whisper Trim™ III or WhisperFlo™ cages and an expanded outlet design work together to significantly reduce operational noise .
Robust Construction: The design mitigates gasket sealing problems from thermal expansion, ensuring long-term integrity .
Superior Sealing Options: Optional ENVIRO-SEAL™ or HIGH-SEAL packing systems provide exceptional leak prevention and control .
High-Performance Shut-Off: Depending on the model, Class V shut-off is achievable—up to 316°C (600°F) with a spring-loaded seal ring using a PEEK anti-extrusion ring, or at higher temperatures using a bore seal .
Built for Severe Service: Reliable performance in critical and demanding applications, including acid gas environments .
