Gate valves have become established for use at the wellhead, but come with some disadvantages. With the API 6A metal-seated ball valves, we offer a replacement in the same overall length, which brings the following advantages:
For ball valves at the wellhead according to API 6A we offer a standard delivery program.
Our delivery times are approx. 12 weeks.
