Dear Guests, we would like to welcome you to our boot 8243!

DAFRAM S.p.A., founded in 1956, was the first company to manufacture floating ball valves in Italy. The long experience gathered during more than 50 years of activity ensures DAFRAM is one of the most famous and competitive companies in the world.

  • DAFRAM trunnion mounted ball valves are built as standard in accordance with the design requirements of API 6D or API 6A, both in two and three piece bolted construction.

    Independent floating spring loaded seat rings are always in contact with the ball to provide an effective tight seal at low differential pressures.

    At higher differential pressures, the upstream seat ring becomes pressure energised against the ball to ensure the seal, whilst the downstream seat remains spring loaded.

    The whole range may be supplied with two basic seating design criteria:

    - SELF RELIEVING SEATS (standard) providing the self relieving of the body cavity overpressure

    - DOUBLE PISTON EFFECT (upon request) providing a double barrier against the fluid. In this case when the upstream seat fails, the downstream seat ensures the seat tightness (the valve body is equipped with an automatic safety valve to release the body overpressures in case of expanding fluids).

  • Multiport Selector Valves

  • DAFRAM Multiport Selector Valve (MSV) consists in one solid body with eight inlets and two outlets. On request multiport selector valves can be produced with six, ten, twelve or sixteen inlets. The inlets may receive the flow of several lines from wells, whereas the last inlet is usually left free for valve tightness testing and to allow serial connection of multiple MSVs. One of the outlets is common for production, the other outlet is for test purposes. With this configuration seven or more wells are conveyed to the production header through a single body.

    The multiport selector valve can be supplied with manual positioning system or with an intelligent actuator, designed to perform a remote control on the skid.

    One of the main advantages of the multiport selector valve is to have a single operation point in order to control seven or more wells streams: e.g. conventional configurations of production manifolds for seven wells need up to seven operation points using three-way valves and up to fourteen operation points with traditional two-way valves.

  • Fully Welded Ball Valves
    DAFRAM fully welded ball vavles are designed and manufactured completely in-house. Design aims at optimizing valve weight and reduce operation torque. Thanks to internal Welding Department, range of production can reach up to 60 inches size valves....

  • DAFRAM fully welded ball vavles are designed and manufactured completely in-house. Design aims at optimizing valve weight and reduce operation torque. Thanks to internal Welding Department, range of production can reach up to 60 inches size valves.

    Welding machines are able to perform SAW process and PWHT as a fully authomatized process and whole process are performed by certified Personnel. DAFRAM International Welding Engineer is in charge to issue WPS according to Customer requiremnts.

    At the moment, more than 50 different welding procedures (PQR) are available and TPA approved. NDTs on welding are performed by DAFRAM qualified Personnel in order to guarantee best quality of products.
