CTF - Series 35-1 Flanged Duckbill Check Valve
CTF - Series 35-1 Flanged Duckbill Check Valve
Description
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 CTF - Series 35-1 Flanged Duckbill Check Valve is the solution.
Series 35-1 Check Valves are manufactured similarly to the Tideflex® TF-1 Check Valve, with the addition of an integral elastomeric flange. The flange size drilling conforms to ASME Class 125/150# and is also available with DIN drillings and other standard or customized drilling patterns. All Series 35-1 Check Valves are furnished complete with retaining rings for installation.
