Insta-Valve Plus provides a means of a permanent block valve into a pressurized water main with no interruption of flow through the pipe and no reduction of line pressure. The insertion of an Insta-Valve Plus is accomplished through a single circular whole cut (under full line pressure) into the top of the pipe with no reaming.
By stocking 4, 6, 8, 10 & 12 valve body you have a unique valve that will insert into steel, PVC, C-900, Cast-iron, Ductile-iron and A/C by utilizing interchangeable side glands that mate the valve body to the pipeline. These standard bodies can be opened up to fit larger O.D.s such as class 200 A/C pipe. For the 10 and larger valves, standard bodies will fit steel, PVC, C-900, Cast-iron and Ductile-iron.
