Features & Benefits
- Rotating Disc Creates a Different Seating Position Each Time the Valve Is Closed - Adds years of operation without maintenance or replacement.
- Self-Cleaning Seat - Deposits are removed in travel, so nothing builds up on the seat surface that could cause leaks. Discs are free of pockets that could collect solids.
- Independent Wedging Design and Seating Action - For smoother valve opening and closing. Uses less force.
- Discs Are Fully Interchangeable and Reversible - Ensures simple and inexpensive maintenance.
- Optional Flushing Ports - Help clean out the extra waste that can settle in the bottom of the valve.
- Rollers, Tracks, & Scraper System - Available on size 14” and up horizontal valves.
- Bypass Valves - Side or bottom bypass valves on size 16” and up.
