Features & Benefits
1. Cover Seal - EPDM or NBR O-ring seal prevents leakage.
2. Reversible Disc - EPDM or NBR encapsulated ductile iron with integral O-ring bead on both sides.
3. Slanted Body Seat - promotes fast, non-slam closure. 35° from full open to closed.
4. Position Indicator (optional) - provides exterior indication of valve position. Spring-loaded closure device.
5. Stainless Steel Hardware - for corrosion resistance.
6. Body/Cover - Ductile iron for added strength and reduced weight.
7. Non-Clog Body Design - smooth contoured surfaces and 100% port area allows passage of solids.
8. Fusion Bonded Epoxy - NSF-61 certified and conforms to AWWA C550.
9. Backflow Actuator (optional) - used to manually open disc when backflushing is required.
Low-maintenance
• Flapper is only moving part
• Anti-corrosion encapsulation of disc and hinge
• Flapper is accessible through full-size top cover with valve in line
• Reversible disc extends useful life of the flapper
• O-ring seat seal is integrated into flapper
• No scheduled maintenance nor lubrication required
Fast-closing
• Quiet operation with non-slam design
• Reduces likelihood of water hammer
• Disc seated at 45° angle with only 35° travel from fully open to fully close position
• Disc hinge flexes into open position and snaps back into closed position
• Optional spring-loaded position indicator accelerates closing
