Class Information
Number: 29/890.132
Name: Metal working > Method of mechanical manufacture > Valve or choke making > Including metal shaping and diverse operation
Description: Process wherein the valve or choke is manufactured by the combined steps of (1) permanently altering the form, configuration, or contour of the workpiece or stock, with or without removal of material, together with (2) an unlike or different manufacturing step, which second step is distinct from the first step although the second step may also constitute another metal shaping operation.
