ABSTRACT:
A combination pipe cutter and gate valve for plastic pipe insertable into an in service pipe through which a fluid is flowing. The combination pipe cutter and gate valve comprises a valve body, means for securing a valve body around a portion of the plastic pipe into which the valve is to be inserted, a shear disposed within the valve body, means for lowering the shear toward the pipe and a cutting element secured to the leading edge of the shear, the cutting element forming a single cutting edge having a length such that the pipe is completely severed after the shear has passed completely through the pipe. As the shear passes through the pipe, the plastic material of the plastic pipe is deformed forming a seal against the faces of the shear.
