Varco Supply carries two brands of brass piston valves: Rubinetterie Italiane Velatta (RIV) and Metaltecnica (MZ). RIV and MZ are two industrial Italian manufacturers with over 130 years of experience in the wastewater industry combined! Though they make near identical brass valves it should be noted that spare parts for rebuilding these valves are name brand specific and NOT interchangeable. |
