Title: Valve positioning handle

Abstract: A valve positioning handle is for a plastic valve which is capable of being utilized in gas distribution pipes and includes a body and a fluid isolation member rotatably disposed therein. If the valve becomes jammed, it and/or the pipe are capable of being destroyed by the application of excessive forces to the isolating member and the body during rotation. The valve positioning handle includes an extended fitting centrally aligned with the isolation member and has a number of working surfaces thereon for the receipt of different torque applying tools. A connecting section between the extended fitting and the isolation member is designed to fail prior to the generation of any excessive forces which might destroy the valve or pipe by a tool being utilized to rotate the fitting.
