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 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
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.
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
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
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.
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
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.
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.
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.

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's factory is located in Urbisaglia (Macerata), the centre of Italy in an industrial complex covering 32.000 square meters, 12.000 of which are covered workshops. The factory consists of commercial, technical and engineering offices and of two extremely modern workshops, the latest of which, 4200 square meters, 10 meters high, completed in February 2008, allows the production, assembly, testing, sandblasting and painting of ball valves up to extremely large sizes and weights.

DAFRAM successfully completed the design and construction of complete skids for the Garraf Project phase 4 for Petronas. The skids are packages made up of a compact manifold, which includes the multiport selector valve, electric actuator, inlet and outlet pipes and a self- contained structure for an easy transport, installation, commissioning, operation and maintenance of the entire system.
DAFRAM in collaboration with TRE P Engineering has developed a web tool (based on IEC 60534 - Industrial process control valves international standards) through which end users, engineering companies and valve specialists can approach the sizing of control valves. The web page (www.controlvalvesizing.eu) is presented as a classic data sheet for control valves, in which the main operating parameters requested for the specific application could be entered as an input. In a few seconds a response about the different types of DAFRAM Control Valves that can satisfy the requirements of the process is given as an output.
This is to be considered as a first approach to the use of DAFRAM control valves, the further step will be a direct contact with DAFRAM technical and sales engineers to thoroughly study the best solution for each customer’s application.
