BUTECH SUBSEA VALVES

BuTech subsea valves meet performance, safety and reliability expectations in
the deepest water and some of the harshest environments in the offshore oil
and gas industry. As wells have become deeper BuTech has been a leader at
developing new and innovative ways to control the increasing temperature and
pressure requirements at these greater depths.
