cost-effective solution to flow control problems
The TF-1 slip on duckbill check valve has a 100% rubber construction that is available in several classes of elastomers for various temperature and chemical combinations. The TF-1 duckbill check valve is designed for end-of-pipe outfall and manhole installations. As a result, the TF-1 duckbill check valve's versatility makes it a popular Tideflex product, suited for backflow prevention and flow control alike.
The Series 35-1 flanged duckbill check valve is optimal for situations not suited for slip-on check valves – usually because the piping or outfall system already has a flange. The uniform body design of the Series 35-1 duckbill check valve is comprised of a rubber duckbill check sleeve, and is low maintenance. It is ideal for tough sewer system control, storm sewer overflow and corrosive slurry applications.
The Series 37G rubber duckbill check valve is an internal duckbill check valve model that can be directly placed inside a pipe. The simple and maintenance-free design makes the Series 37G a choice rubber duckbill check valve for combined sewer outflow applications. Moreover, the Series 37G internal duckbill check valve does not require an outside power source to operate.
The Series 37 rubber duckbillcheck valve is ideal for installations between two mating pipe flanges, fitting seamlessly with minimal protrusion. The Series 37 duckbill check valve is available in several classes of rubber elastomers for various chemical and temperature handling needs. This is an ideal backflow prevention valve.
A historic slip on rubber duckbill check valve, the TF2 duckbill check valve was Tideflex Technologies' first valve created in the 1980s. The TF2 slip on duckbill check valve comes in a variety of elastomer choices, and is engineered specifically as a backflow prevention valve.
The Waterflex check valve is suited for drinking water applications. This check valve is fitted with an elastomer disc that can be manipulated with hydraulic pressure. Forward hydraulic pressure enables flow through the perforated plate interior, while reverse hydraulic pressure seals the disk against the plate for optimum backflow prevention. The Waterflex check valve comes in flanged and mating valve insert styles.
Tideflex Technologies All Rubber Duckbill Check Valves are a revolutionary design for backflow prevention. Tideflex Duckbill Check Valves require no routine maintenance or repair due to their all-rubber construction.
Tideflex valves are substantially more cost efficient than conventional check valves. They are totally passive valves, operating solely on line and back pressure, and require no outside energy source for operation. Sliding, rotating, swinging and plunging parts are completely eliminated.
Tideflex valves are excellent replacements for ineffective flap gate valves. Millions of dollars each year are lost in the re-treatment of unnecessary backflow because of faulty check valves which have corroded open or have been wedged open by debris. Tideflex® duckbill check valves seal and close drop tight around debris with less than 1 psi of back pressure.
Tideflex® valves will not warp or freeze, and are virtually maintenance free. They will handle large obstructions without jamming, and there is no gate to hang open. Tideflex® valves are easily banded on the end of the discharge or storm sewer line, eliminating the need for headwalls.
