Georg Fischer 9854-080 8 Inch Cpvc Van Stone Flange Sch80

Product Description

The GEORG FISCHER 9854-080 is an 8-inch Class 150 Schedule 80 CPVC van stone flange rated for 150 PSI at 73 degrees F. Van stone flanges feature a loose backing ring design that allows the flange face to rotate freely, making bolt-hole alignment fast during installation. Fabricated from Corzan CPVC, this flange resists a broad range of corrosive chemicals and high-temperature process fluids. It is a fit for industrial and commercial piping systems where a durable thermoplastic flange is required at standard ANSI 150-pound bolt patterns. Licensed plumbers and pipefitters are the primary installers of this fitting.

This flange is suited for use in chemical processing, water treatment, industrial plumbing, and commercial mechanical systems where CPVC Schedule 80 piping is specified. The 8-inch size handles large-diameter runs where corrosion-resistant thermoplastic flanging is preferred over metal alternatives. Systems operating at or below 150 PSI at 73 degrees F fall within the rated service conditions of this fitting. Corzan CPVC construction supports elevated service temperatures beyond what standard PVC allows, making it a common choice in hot process lines.

Key Features

• Rated at 150 PSI at 73 degrees F for reliable pressure-rated service
• Schedule 80 wall thickness for added strength in demanding applications
• Van stone rotating face design simplifies bolt-hole alignment during installation
• Corzan CPVC material provides broad chemical resistance and elevated temperature performance
• Class 150 ANSI bolt pattern for compatibility with standard 150-pound flanged components
• Large 8-inch nominal size serves high-flow industrial and commercial piping runs

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 80 CPVC piping systems using Class 150 ANSI-pattern flanged connections at 8-inch nominal pipe size.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter familiar with thermoplastic flanged piping systems. Depressurize and drain the line fully before removing or installing any flanged connection. Use appropriate flange gaskets and fastener torque sequences per the system design engineer's specifications and applicable plumbing codes such as the IPC. Do not exceed the rated pressure or temperature limits of the fitting, as CPVC is subject to derating at elevated temperatures.
