Series 37G
Series 37G
Enquire about this ProductThe Tideflex Series 37-G is a special adaptation of the Series 37. The 37-G can be completely inserted into a pipe which effectively gives it a zero face to face dimension. The outside diameter of the 37-G’s cuff is fabricated to precisely match the inside diameter of the pipe, providing a press-fit. The valve is supplied with an internal expansion clamp to provide compression between the valve and pipe ID. The 37G can even be fabricated for elliptical or out of round pipe (consult factory for special fabrications). As with the Series 37 the “bill” does not flare and the headloss of the 37-G is higher than other styles of Tideflex. The 37-G is predominantly used in gravity-driven outfall pipes and in manholes and vaults where the valve is inserted into the effluent pipe and compressed to the pipe ID with the expansion clamp. The 37-G can be inserted into the end of a pipe, but access to clamp should be from upstream of the valve, not thru the “bill” of the valve. For those applications where there is no access to the upstream side of the valve, the 37-G Thimble Insert is the solution. The Tideflex Duckbill Check Valve is a revolutionary design for backflow prevention. Tideflex Valves are a one-piece rubber matrix of numerous natural and synthetic elastomers and ply reinforcement, similar in construction to a truck tire. Tideflex are cost-effective because they do not need periodic maintenance or repair to keep them operational and they have a 30 year operational life span. Tideflex operate using line pressure and backpressure to open and close so no outside energy source is required. The valve has an extremely low cracking pressure so the valve self-draining which eliminates standing water and maximizes storage volume in the upstream pipe. Tideflex Valves have low headloss, they do not rust or corrode and are not affected by UV so performance and reliability is constant thru the life of the valve. The flexibility of the Tideflex allows the valve to compress around trapped solids providing a much better seal than flap gates, as confirmed by the USEPA. With the development of the patented curved bill, sealing capabilities are even further improved because the curve bill is more flexible than the rest of the valve and therefore compress more around solids. For higher backpressure ratings or to lower headloss while maintaining backpressure ratings, the Saddle Support Technology (SST) can be used in conjunction with the Series 37-G.
