Fisher 8590 High Performance Butterfly Valve
The Fisher 8590 high performance Butterfly valve maintains tight shutoff and can be specified for a wide range of pressure and temperature conditions. The 8590 valve is available in a lugged body design.
FEATURES
1.This valve will meet your actuator needs with a choice of splined, square, or keyed shaft connections.
2.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.
3.The optional ENVIRO-SEAL™ packing systems are designed with very smooth shaft surfaces and live-loading to provide improved sealing, guiding, and loading force transmission.
4.Trim and bolting materials are available for applications involving sour liquids and gases.
5.The valve body self-centers on the line flange bolts as a fast, accurate means of centering the valve in the pipeline.
6.Seal retainer screws are located so there is no interference with the sealing function.
