Abstract: The present invention discloses a method and a holding device(100) for performing edge preparation of forged steel valves. The method comprises performing a milling operation in the casing(02) for locating a valve assembly(01). Tapped holes are defined in the valve assembly(01) for clamping the valve assembly(01) to the casing(02). A first boring operation is performed in middle of a casing(02) to accommodate a valve body(07). A second boring operation perpendicular to the first boring operation is performed to accommodate a valve yoke(08). The valve assembly(01) is locked to the casing(02) using a safety clamp(03). The holding device(100) comprises the casing(02) defining the first bore and the second bore. The first bore accommodates the valve body (07) and the second bore accommodates the valve yoke (08). The safety clamp(03) locks the valve assembly(01) to the casing(02). A lifting eye blot(05) is configured to lift the holding device (100).
