s.24 DZR

Info request

full port 1/2"- 4" dezincification-resistant
hot forged ball valve

Several governmental authorities recommend use of special alloys for valves handling water in areas where there is a problem of dezincification. RuB DZR valves are designed to meet such requirements.

Through the use of new technology these valves retain the reliability and competitiveness of brass, but are comparable to bronze in corrosion resistance.

Be kind with yourself, make sure the valve that brings you pure fresh water is an RuB DZR valve.
