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. Features 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.
