• TWIN BALL DB&B VALVES

  When assured valve shut off and absolute isolation are required, DAFRAM provides Double Block and Bleed valves that consist of two main in-line isolation valves and a bleed valve, used to drain or vent trapped fluid between the two obturators.

• SUBSEA BALL VALVES

  DAFRAM subsea ball valves are available in different construction versions: bolted-body side-entry or top-entry and fully welded body.  As a standard, valve design, materials and testing are according to API 6DSS but the most demanding Customer specifications can be met upon request. Hyperbaric test is also available at DAFRAM Testing Department.

• Control Valve

  Due to a very large flow passage DAFRAM control ball valves can grant high flow coefficients compared to other valve types. Thanks to their operating principle, quarter-turn ball valves are able to control fluid flow at very small openings and to open at high differential pressure.
