Corporation Valves

Machine inserted corporation stops were developed by Mueller Co.’s founder Hieronymus Mueller in conjunction with the development of the drilling and tapping machine used to make pressure taps in water mains. Mueller Co. offers corporation stops in three types: machined key (e.g. ground key), ORISEAL®, and ball. All three designs are available with a wide range of inlet/outlet combinations including the Mueller 110® compression, grip compression, and pack joint connections. These three designs are all compatible with Mueller’s complete line of drilling and tapping machines, and small drilling machines. All service brass will comply with AWWA C-800. Components in contact with potable water also comply with latest requirements of the Federal Safe Drinking Water Act.
