Frequently Asked Questions

What sizes and pressure classes of forged ball valve bodies do you produce?

Bodies and covers for two-piece and three-piece ball valves from 1/2" to 12", in pressure classes Class 150, 300, 600, 1500 and 2500, both floating and trunnion mounted.

Which materials do you forge?

Carbon and low-temperature steel, alloy steel, stainless, duplex and super duplex, nickel alloys, and power-plant and structural grades. The full list, with the service each grade suits, is on the forged materials page.

Do you supply as-forged parts or finished machined parts?

Both. Parts can be supplied in as-forged condition or finish-machined to your drawing, including shot blasting, dimensional inspection and reporting.

Can you forge to a customer drawing, or only standard sizes?

Custom work is our normal business. Send the drawing (PDF or DWG) and we review die-forging feasibility, propose the process, and quote. Drawings and custom sizes are welcome.
