By-pass valve is a drilling tool mainly used for workover in gas well and high pressure oil and gas well.

It is usually located to the upper end of the tools (drill bit, taper tap, and spear type fishing tools, etc.).

It only performs as a sub in normal drilling or releasing fishing operation.

When overflow occurred, and downhole drilling tool is unable to achieve normal circulation and well killing operation, the By-pass Valve can be opened to accomplish outer circulation and well killing.

To avoid the sticking accident in workover operation, the By-pass Valve is used to achieve outer circulation, which is convenient, safe and reliable.
