ABSTRACT:
A valve assembly adapted to be emplaced upon a pipe comprises a housing having a bore extending perpendicular to the pipe to which the valve is to be connected and serving as a guide passage for a drill adapted to penetrate the pipe wall. The housing is formed with a transverse slot through which a slider can be inserted to block escape of fluid from the passage upon withdrawal of the drill. The control member is then mounted in this passage and can be used to open and close the valve which communicates with the pipe to which the valve connects via the aforementioned slot.
