Drum, Barrel and Backflow Valves (Industrial)
Similar to plain Check Valves, Backflow preventors prevent water from cross-contaminating the supply (typically drinking, potable city water) and are required for cross-connection in many cities. They are designed for more precise, serviceable potable water applications as opposed to standard industrial check valves. In this section we also offer miscellaneous drum dispensing valves and wrenches.
