Valve body with identification tab

A pipe system comprising:

• a first flange defining a first flange face and a first flange surface, the first flange defining a fastener hole extending through the first flange from the first flange face to the first flange surface, the fastener hole defining an axis;
• a second flange fastened to the first flange by a plurality of fasteners;
• and
• an identification tab disposed on the first flange, the identification tab defining a planar indicia surface axially positioned between the first flange face and the first flange surface, the indicia surface defining indicia recessed into the indicia surface, the indicia indicating a torque specification for fastening the first flange to the second flange with the plurality of fasteners.

A method for forming a valve body, the method comprising:

• pouring a molten metal into a valve body mold cavity of a mold;
• forming a flange and an identification tab within the mold, the identification tab disposed on the flange, the flange defining a flange face and a flange surface, the flange defining a fastener hole extending through the flange from the flange face to the flange surface, a bore extending through the flange, the bore defining an axis, the identification tab defining a planar indicia surface, the indicia surface axially positioned between the flange face and the flange surface relative to the axis, the indicia surface defining indicia recessed into the indicia surface;
• and
• removing the valve body from the mold.
