Features & Benefits
- Long-Term Reliability and Quiet Operation The hinge bushing features oil-embedded bearing bronze, a premium material known for its exceptional wear and corrosion resistance.
- Engineered for Durability Our frame and cover are precision-crafted from high-strength ductile iron, delivering the rugged durability of steel with the versatility and flexibility of cast iron.
- The 2.5° Seat Angle Advantage This subtle design feature ensures positive closure by harnessing gravity and flow dynamics to guide the gate into a secure, leak resistant seal every time.
- The Secret Formula for Pump Discharge Applications Our pump discharge solution combines a spring bumper, neoprene seal, and 125-pound flange to deliver unmatched reliability – reducing wear and preventing the flap from overextending.
- Superior Bronze Seals for Corrosive Environments Bronze’s exceptional resistance to corrosion – from saltwater, chemicals, and acidic conditions – ensures seal integrity and functionality over time, even in harsh elements.
