    COMPANY PROFILE

    After starting with the production of seats with soft and metallic seal, Cober subsequently developed into the production of Trunnion and Floating spheres with two or more ways. We are now able to supply complete kits (ball and seats) for ½ “to 72” ball valves for all types of applications. Our production takes place on two production plants, where more than 60 highly qualified operators work. Thanks to over 40 years of experience and our fleet of machines, we are now able to do all kinds of precision machining up to 3000mm.
