Description
The 2500 body is a durable, solid ring type body that is machined for accurate disc alignment. Standard body wall thicknesses vary according to static pressure and flange rating. The body is designed to with-stand stresses imposed upon it, through pipe flanges. Each disc is fabricated with precision machined and specially finished tolerances preventing shaft distortion and disc misalignment. Ample metal is provided in the hub to maintain rigidity and strength of the disc and its components. The shaft cam be either one piece or stub shafts. Bolting holes are located in valve body where optimum strength requirements provide maximum support to the total valve assembly. Two or four body holes are dimension according to USAS Code flange standards depending on valve size.
