VALVOSIDER

Valvosider was formed in 1951 as a manufacturer of valves operating on oil & gas, petrochemical and chemical industries as well as on power-stations plants.
After more than 50 years of continuous growth, Valvosider has became a "VALVE MANUFACTURER" of international reputation.

Valvosider S.r.l. is committed to providing its clients with a product which conforms in every respect both to the requirements of the contract and the client's needs at a fair cost, within the contractual delivery time, with the highest possible safety standards, while at the same time protecting the well-being of the natural environment and the community where the materials are being produced.


To accomplish this the General Management has set up a Quality System which operates in conformity with ISO 9001 standards. This system has been designed in such a way so that it may be modified and improved at any stage of the production cycle, whilst also ensuring the professional and technical development of our staff.


The Managing Director has the ultimate responsibility for the development and implementation of the Quality System.


This responsibility has been delegated to the Quality Manager, who has full authority and autonomy to develop and maintain the Quality System. The Managing Director requires that all members of the company comply with the procedures laid down in the Quality System Manual.


All management levels are responsible for ensuring that the requirements of the Quality System Manual are both understood and observed. All employees engaged in the manufacture of goods in Valvosider's name are responsible for producing a quality product that meets the client's specified requirements.
