MARSHALLTOWN, IOWA (March 12, 2009) -- Emerson Process Management announces the release of the Fisher® 8580 rotary valve that delivers rugged reliability and high cycle life, increasing plant availability.
Extensive laboratory verification was performed on the Fisher 8580 to ensure reliability. Mechanical tests were conducted to determine cycle life, fatigue life, vibration resistance, temperature limits, and pressure limits. In addition, tests were performed on materials for the Fisher 8580 valve body, disk, seals, shaft, and bearings to assure resistance to conditions that could lead to deterioration in performance.
The new rotary valve can easily be installed in either a horizontal or vertical orientation with no detriment to performance or cycle life. This also enables left- or right-hand mounting of the valve actuator, allowing access for any installation.
The Fisher 8580’s disk design gives it an approximately linear flow characteristic to provide precise throttling control. The valve is offered with either a soft or metal seal, providing capability for enhanced shutoff. The interchangeable seal capability minimizes parts inventory requirements.
To facilitate use in all world areas, the Fisher 8580 meets API, ASME, and EN standards. The valve body meets PN 10 through PN 40, CL150, and CL300 ratings. Face-to-face and raised-face dimensions meet EN 593, API 609, and MSS-SP68 standards.
