Founded in 1963 by Dario Mariani, a man of dynamic and entrepreneurial personality, Mariani was created and developed with the specific determination to respond to the multiple demands of the market, with a wide range of high quality valves and taps. Since the beginning of its activity, Mariani has given the utmost importance to the concept of “qualityâ€. The CQ organization, which guarantees scrupulous observance of the design, construction and testing procedures according to the ISO 9000 standard, also allows the production of valves intended to undergo the most severe operating conditions (chemical industries, off-shore platforms, thermal or nuclear power plants) in compliance with international standards: API - ASME - ASTM - BSI - DIN - MSS. The originality of the company is to be able to react effectively, both to requests relating to small qualities and special executions, and to offers requiring larger quantities or series.
