Fisherr 8580 Rotary Valve

The Fisher 8580 rotary valve offers excellent throttling

performance. An approximately linear flow

characteristic provides precise throttling control. The

8580 valve offers high cycle life and rugged reliability.

The valve body meets PN 10 through PN 40, CL150,

and CL300 ratings. Face-to-face dimensions meet EN

558, API 609, and MSS-SP68 standards. Line centering

clips provide for versatility to mount and align the

same wafer style valve body in different piping

configurations (ASME and EN ratings).

The 8580 rotary valve features an eccentrically-

mounted disk with either soft or metal seal, providing

capability for enhanced shutoff. The interchangeable

sealing technology allows for the same valve body to

accept both soft and metal seals.

The actuator sizing and selection process is improved

by simply reading a table for information.

8580 Features

 Approximately linear flow characteristic– An

approximately linear flow characteristic provides

precise throttling control.

 Global Stand ards– The valve meets API, ASME, and

EN standards, making it suitable for use in all world

areas.

 PEEK/PTFE bearing as standard– The PTFE-lined

PEEK bearing is a low friction, low wear bearing. I t

allows the valve to operate under high pressure

drops for a high cycle life while maintaining low

torque. The “drop-in” bearing design enables fast,

easy maintenance.

 Spline-ended Shaft– The splined shaft with clamped

lever and single-pivot linkage reduces lost motion

between the actuator and the valve shaft.

W9425-2

SINGLE FLANGE STYLE

W9498-2

 Improved shaft-disk pinning– The improved

expansion pin system ensures t here is a positive,

durable connection between disk and shaft. This

connection reduces backlash and wear in the drive

system, optimizing long-term performance. It also

makes disassembly for maintenance quick and

simple with no need for special tools.

This complements the ability to mount the actuator on the left- or right-hand side, enabling access for any installation.

8580 Valve D103299X012 Options Top-Mounted Handwheel: For infrequent use as a manual actuator (see bulletin 61.1:2052, D103295X012). For repeated or daily manual operation, the unit should be equipped with a declutchable handwheel actuator. Declutchable Handwheel Actuator: An end-mounted manual actuator can be used to provide on-site control and to provide override capabilities. See bulletin 61.8:1078 for handwheel actuator specifications.
