Description
Fisher 8590 High Performance Butterfly Valve
Applications
- Cryogenic
- Chemical and petrochemical
- Power and heating
- Pulp and paper
Special Features
- The valve body self-center’s on the line flange bolts as a fast, accurate means of centring the valve in the pipeline
- Seal retainer screws are located so there is no interference with the sealing function
- The torque necessary to open and close the valves is the same, regardless of the direction in which the differential pressure is applied
- The pressure-assisted seal design provides tight shutoff and permits the use of smaller, less expensive actuators in applications requiring full ASME B16.34 shutoff capabilities
- This valve will meet your actuator needs with a choice of splined, square, or keyed shaft connections
