Series 35-1 Flanged Tideflex duckbill check valve with curved bill

In some applications, a slip-on Tideflex duckbill check valve (TF-1) is not feasible because of an existing mating flange or wall thimble, or a flanged connection is preferred, or it is desired to mount the valve directly to a concrete wall. In these cases, the 35-1 Duckbill Check Valve is the solution.
