Valve Insertion
A Valve Insertion is an installation of a valve onto an existing pipeline with no service interruption or depressurization. This can be used to prevent shutting down an entire main line while providing a valve to be used in the future as well. It requires 120 degrees of rotation (pictures provided below) to create a full slit in the pipe for the permanent valve.

First, a sleeve is mounted on the pipe in the desired location for the valve, followed by mounting brackets, and then the motor on top. A chain and crank are attached for rotating the valve/sleeve and a blowoff hose for shavings is inserted.

After everything is mounted, the motor drills a hole directly into the pipe and is then locked into place. The crank then turns the sleeve 120 degrees (with precautions) while the motor is running, cutting a long slit into the top of the pipe.

Once the cut is completed, the temporary valve is closed so that the bonnet can be mounted in place of the motor. The entire valve is then bolted down with mega lugs and checked for shutdown. The entire process takes under 2 hours and leaves only the sleeve and valve bonnet.
