Fisher™ 8580 High Performance Butterfly Valve

The Fisher 8580 high performance Butterfly valve provides the capability for enhanced shutoff and features an eccentrically-mounted disk with either a soft or metal seal. Experience excellent throttling and on/off performance with this control valve.

• The actuator/valve assembly action can be converted from push-down-to-open to push-down-to-close; or vice versa; without additional parts.
• Both the metal and soft seal rings have pressure-assisting sealing action that ensures tight shutoff regardless of pressure drop.
• Standard valve construction includes conductive packing to provide electrical bonding for hazardous area applications.
• The valve will operate at elevated temperatures; with the appropriate trim components.
• Additional travel indication can be achieved by using the indication line on the shaft; along with the disk position markings on the packing follower.
• Redundant shaft retention provides added protection. The packing follower; anti-blowout ring; and shaft groove interact to hold the shaft securely in the valve body.
