The Company

CMD, a Company that is more and more appreciated by the most qualified valve manufacturers all over the world, was established in 1989 by Mr. Luciano Ghirardelli and is based in Cologne, a small village located in the northern Italy.

Mr. Ghirardelli’s idea was to bring his long experience in the gasket world into the use of such an outstanding and precious material, as he sensed that the graphite could win the most exciting challenges at the most extreme conditions.

The Company is run by Luciano’s son and daughter, Claudio and Danila, together with their families and still enjoys the advantages of a family-led organization combined to all necessary industrial aspects in projecting, consultancy, technical support, administration and commercial procedures that ensure a perfect product process from scratch to the final user.

In fact, CMD’s procedure system is UNI EN ISO 9001:2008 certified since 1996.

Our spiral wound gaskets, graphite rings and stem packings, among the others, achieved the total esteem of the valve industry, proved by the most respectable world certifications such as Shell SPE 77/312 Class A and Class B, API Standard 622, VDI 2440 (TA Luft) and ISO 15848, obtained by the most qualified valve manufacturers, thanks to the superlative performances our gaskets allow.

We underwent very severe tests and rewards come as a consequence when quality is a priority. To mention one, CMD was recently appointed as Qualified Supplier by Petrofac.


The constant care for the future production is the real success at CMD and all departments strive for the continuous innovation.

Some of our products are registered trademarks and were conceived by the constant exchange of experience with the technical offices of our Customers.
