Description

The 8580 rotary valve offers excellent throttling and quarter-turn performance. An approximately linear flow
characteristic provides precise throttling control. The 8580 valve offers high cycle life and rugged reliability.
Retainer clips provide for versatility to mount and align the same wafer style valve body in different piping
configurations (ASME and EN ratings). The valve body is compatible with PN 10 through PN 40, CL150, and CL300
ratings. Face-to-face dimensions meet EN 558, API 609, and MSS-SP68 standards.
The 8580 rotary valve features an eccentrically-mounted, double-offset 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.
