Insert Valve Development and Offers

International Flow Technologies, Inc. (IFT) has had a crucial role in the development of the Insert Valve. IFT worked alongside the design engineers to help create a resilient seated insertion valve of simple design that meets and/or exceeds the AWWA C515 specification. Easy to install into pipeline systems without a shut down and capable of handling working pressures up to +250psi, this valve changes the course of insertion valve technology. We offer installation of 4", 6", 8", 10" & 12" onto Steel, PVC, C-900, Cast-Iron, Ductile-Iron and A/C by utilizing interchangeable side glands that mate the valve body to the pipeline.

Other Insertion Valves

International Flow received a call from Rancho Water Company in Temecula, CA about their pipeline that had no pipe to perform a Linestop except a 24" 90 degree elbow. It was a fabricated sectional elbow as well! !

The 24" Plug valve was seized in the closed position, with no way to isolate, and the only option was to bypass the operational sewage plant.

Seeing the importance of this valve replacement, International Flow laid out the easiest way to isolate the 24" pressurized sewage elbow without building specialized machinery. Another concern of IFT was to check the inside of the pipe for the possibility of it being filled with solids making it hard to install a linestop mechanism. The condition of the pipe was checked by sending a measuring probe through a test hot tap and the line seemed to be full of sewage, but only 20% solids were resting on the bottom of the pipe. So the operation was full steam ahead!
