8. CSO / SSO Backflow Prevention
Larflex valves prevent the backflow of clean water into the overflow pipes of Sanitary Sewer Overflow (SSO) and Combined Sewer Overflow (CSO)
When flap gates fail, backflow occurs and treatment plants are forced to treat the clean water because it has combined with sewage
The persistent operational problems with flap gates, and resulting high maintenance costs, resulted in the US EPA issuing a grant to develop an "All Rubber Duckbill" to overcome problems with flap gates

For Combined Sewer Overflow

9. 42” Flanged Installed for
Flood Control Systems
Flood control systems often incorporate multiple high volume / low head pumps in order to discharge large amounts of water rapidly
Although the differential pressure is not great, these systems are often susceptible to backflow during high tides and storm surge
Larflex valves are integrated into flood control systems due to their low headloss and reliable backflow performance
These systems cannot take the risk of using rigid flap gate technology because of their history of not sealing, corrosion problems, and tendencies to freeze open or shut closed

Flood Protection

10. Levee Flood Protection
Drainage pipes penetrate levee embankments to allow storm water runoff relief
It is crucial to have the reliable backflow prevention capability of Larflex valve to prevent flooding of residential and commercial areas when the discharge pipe becomes submerged

The Larox valve utilizes two pinch bars which squeeze the sleeve from opposite sides closing the valve on the centerline
Having two moving pinch bars which stretch the rubber sleeve creates a significant advantage compared to single pinch type pinch valves
The stretching action of two pinch bars create less stress on the rubber sleeve and also insures a stretching and cleaning of the inner layer of the pinch valve sleeve. With each and ever operation the pinch valve sleeve is cleaned free of lime slurry scale build up
Larox offers its SensoMate option which is a wear monitoring system built into the structure of the rubber sleeve
Larox pinch valves are engineered to be the best available pinch valve in the industrial market today
Larox pinch valves dwarf the pressure capabilities of traditional pinch valves. The Larox pinch valve is capable of handling pressures up to 1500 psig
