The Fisher™ 8580 High Performance Butterfly Valve is engineered to deliver exceptional throttling performance and reliable shut-off in a wide range of process conditions. Featuring an eccentrically mounted disc, this control valve provides a near-linear flow characteristic for precise modulation, making it suitable for both control and isolation duties .
Built for durability and long service life, the 8580 valve incorporates a robust design with features like a patented low-friction PEEK/PTFE bearing, which allows for high-cycle operation under significant pressure drops while maintaining low operating torque . Its splined shaft end minimizes lost motion between the actuator and valve shaft, ensuring responsive control . For enhanced environmental safety, the optional ENVIRO-SEAL™ packing system utilizes a smooth shaft surface and live loading to control emissions effectively, keeping them below 100 ppm .
Key Advantages:
Precise Flow Control: The near-linear flow characteristic ensures accurate and predictable throttling performance .
Tight Shut-Off: Pressure-assisted seals, available in both soft (e.g., PTFE) and metal types, provide excellent bidirectional shut-off, achieving up to Class VI (per FCI 70-2) .
Robust and Reliable: Constructed with materials like carbon steel and stainless steel, the valve is designed for high cycle life and rugged reliability .
Easy Installation and Maintenance: The valve body self-centers on pipeline flange bolts for simplified alignment . The improved expansion pin system allows for easy disassembly without special tools .
Global Compliance and Versatility: The valve conforms to international standards including ASME, EN, and PED . It is also suitable for sour service applications, complying with NACE MR0175/ISO 15156 .
