Introduction

Scope of Manual

This instruction manual includes installation, maintenance, and parts information for the Fisher 8590 valve, NPS 3
through NPS 24 (figure 1). Refer to separate instruction manuals for information covering the power actuator and
accessories.
Do not install, operate, or maintain an 8590 valve without being fully trained and qualified in valve, actuator, and
accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is important to

Description

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. A splined shaft can combine with a variety of
spring-and-diaphragm or pneumatic piston actuators. A square or keyed shaft can combine with a variety of
handlevers, handwheels, or pneumatic piston actuators. These combinations help make the 8590 valve a reliable,
high-performance butterfly valve for both throttling and on-off applications in the process industries.
