NOV (Shaffer)

By continuously increasing the breadth and depth of products and services offered, National Oilwell Varco (NOV) is one of the world’s three major blowout preventer manufacturers. NOV has become the steward of more than 40 industry-leading brand names, one of which is Shaffer, throughout the past 140 years.

Among these strategic mergers and acquisitions are some of the leading names in the upstream oil and gas industry. This has allowed NOV to offer a full line of high-quality products and solutions. The Shaffer record of reliability in pressure control equipment is the result of continual research and development, advanced manufacturing techniques, stringent quality control and steady follow-through on after-the-sale training, service and parts. This reliability is available in ram, annular and rotating blowout preventers.
