cryogenic valve Italy

...For over 90 years, we have been producing industrial valves in bronze and brass, shut-off valves for transformers, globe valves, flanged and threaded filters, needle valves, check valves, flap valves, male and stop taps, flow and level indicators. Design, casting, machining, assembly, and testing: everything is strictly carried out in-house in accordance with ISO 9001 and 14000 standards. The foundry, specialized in cryogenic valve castings, is TÜV certified and equipped with shell moulding and 'green' sand facilities.

... international standards. The prediction of stress levels and corresponding deformation using the Finite Element Method is part of our standard procedures for designing and verifying valve components. DAFRAM's quality assurance system was first certified in 1988 by RINA. Today, the entire design, manufacturing, and testing process is covered by a certified quality assurance program that is continuously verified by accredited inspection bodies.

... contaminated fluids. Thanks to their special design, coaxial valves are maintenance-free. The coaxial valve design allows fluid flows in both directions. The valves can therefore be alternately traversed. The extremely compact and pressure-balanced design enables the fastest switching operations. The corresponding coaxial valves achieve reproducible switching speeds of 25 ms.
