FISHER 8580 VALVE BUTTERFLY VALVE – PRODUCT FEATURES

• Global Standards – the valve meets API, ASME, and EN standards, making it suitable for use in all world areas
• PEEK/PTFE bearing as standard – the PTFE-lined PEEK bearing is a low friction, low wear bearing. It allows the valve to operate under high pressure drops for a high cycle life while maintaining low torque. The “drop-in” bearing design enables fast, easy maintenance
• Spline-ended Shaft – the splined shaft with clamped lever and single-pivot linkage reduces lost motion between the actuator and the valve shaft
• Improved shaft-disk pinning – the improved expansion pin system ensures there is a positive, durable connection between disk and shaft. This connection reduces backlash and wear in the drive system, optimizing long-term performance. It also makes disassembly for maintenance quick and simple with no need for special tools
• Easy Installation – line-centering clips engage the line flange bolts to simplify installation and provide for centering of wafer-style valves in the pipeline. End connections are compatible with EN and ASME standards
• Excellent Shutoff – both the metal and soft seal rings have pressure-assisting sealing action that ensures tight shutoff regardless of pressure drop
• Long Seal Life – the opening and closing path of the eccentric disk minimizes disk contact with the seal ring, thereby reducing seal wear, undue friction, and seating torque requirements
• High Temperature Capability – the valve will operate at elevated temperatures, with the appropriate trim components
• Excellent Emissions Capabilities – the optional ENVIRO-SEALt packing systems, are designed with very smooth shaft surfaces and live-loading to provide improved sealing, guiding, and loading force transmission. The seal of the ENVIRO-SEAL system can control emissions to below 100 ppm (parts per million)
