  • TWIN BALL DB&B VALVES

    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.

  • TOP ENTRY BALL VALVES

    TOP ENTRY BALL VALVES

    Top-entry construction is also available for special applications such as: Sour service ball valve, High temperature ball valve, Cryogenic ball valve, Underground ball valve, Metal Seated ball valve, High Alloy ball valve.

  • SUBSEA BALL VALVES

    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.

  • HIPPS VALVES

    HIPPS VALVES

    DAFRAM valves for HIPPS applications are specifically designed in order to meet very strict requirements given by International Standards and service conditions. Special attention is dedicated to valve drive train design and seat materials selection because of the considerable speed of shut down operation.

  • TRUNNION BALL VALVES

    TRUNNION BALL VALVES

    ABRASIVE SERVICE, HIGH TEMPERATURE SERVICE, CRYOGENIC SERVICE, SOUR SERVICE (API 6D, 7.7), CORROSIVE SERVICE, EMISSION FREE VALVES, EXPLOSIVE DECOMPRESSION, PARTICULAR FLUIDS, SPECIAL VALVE PATTERN

  • HIGH PRESSURE VALVES

    HIGH PRESSURE VALVES

    Ball valves for high pressure service are according to API 6A standard and available in different construction versions. Quality control level is up to PSL 4 and performance requirements and tests are up to PR2. Special valves for HIPPS application are also available together with operation devices.

  • control valve

    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.

  • RESEARCH AND DEVELOPMENT

    RESEARCH AND DEVELOPMENT

    Five years ago Research & Development Department was created inside DAFRAM Company as a group of young engineers who have the task of studing and testing new materials and processes in order to improve DAFRAM valve quality and performance. Special attention is dedicated to simulation of critical service conditions on prototypes.

  • ENGINEERING

    ENGINEERING

    DAFRAM's engineering department is continually working to innovate, refine and improve products. Our engineers can work with the most advanced software applications such as Autocad, Pro-Engineer, Pro-Mechanica.

  • PRODUCTION

    PRODUCTION

    DAFRAM manufacturing plant is equipped with machines covering the complete valve production range; special machines are dedicated to the production of all the valve components and the whole construction process is executed in DAFRAM plant.
