Abstract

A valve which can be fitted into a pipe-line without interrupting the flow has a body (2) with a cap (1) which is clamped around the pipe. The body (2) supports a gate valve (3) which is opened whilst a boring tool, guided by the upper part of the gate valve, makes a hole in the wall of the pipe. The gate valve (3) is opened to withdraw the boring tool to the upper half of the gate valve and then closed again whilst the tool is removed. These steps are reversed in order to fit the valve head into the body (2) of the main valve.
