The installation process of the present invention consists of a body mounting step (S1), a drilling step (S2), a perforator removal step (S3), a mounting flange installation step (S4), a gearbox mounting step (S5).

The body mounting step (S1) is a step of mounting the body to the saddle mounted on a fluid pipe, such as a water pipe. The body has a flow path of ″ ″, which firmly couples the flange formed at the end of the inlet to the saddle.

The drilling step (S2) is a step in which the drilling is made in the water pipe through the drilling machine. By mounting the knife valve and the perforator sequentially in the control unit of the body, the flange of the control unit is equipped with a knife valve, the perforator is mounted on the other side of the knife valve coupled to the flange of the control unit.
