These place high demands on materials, sealing integrity, and the design of valves. Based on many years of experience in high-pressure and energy technology applications, Hartmann develops specially designed ball valves and wellheads that ensure reliable and efficient process control in CO\u2082 applications, particularly in the dense phase.  <\/p><p>Thanks to their robust design, certified safety, and long service life, our special valves are a reliable solution for your
