2 In the creation of the value chain, of which we feel to be part of, the selection of suppliers of raw materials and semi manufactured is a fundamental aspect: all our suppliers are ISO 9001 certified. Graphite fibres, expanded graphite, steels, PTFE, elastomers and special products are carefully selected and tested for a long period of time. Therefore, good products emerge from good materials! Control Plan of the raw materials To standardize long lasting quality is a daily effort which involves resources, expertise, passion and constant attention. Control Plan of productive processes Our...

Setting Valve 3 An accurate certificate apparatus is essential in the modern commercial dynamics as a guarantee of our products. Our products are provided with certification of FIRE SAFE, LOW EMISSIONS, LONG LIFE and ANTI CORROSION for the LONG TERM. Certification of product Technical competence Carrara S.p.a. has been the first Italian producer to arrange a permanent laboratory in their plants for the tests in helium, to study and develop their knowledge within the field of the Fugitive Emissions. For the continuous expansion of the "Prototype test" of fugitive emissions that valve...
