    Question
    Hi-Flow™ control valves call out ANSI B16.104 Class IV flow leakage. What does this mean?
    Answer
    ANSI B16.104 is a testing specification for control valves. This specification has actually been superseded by ANSI/FCI 70-2 Class IV. The class IV designation defines the allowable amount of leakage through the valve seat in the closed position. Class IV allows for .01 percent of the rated flow (Cv), to pass through the seat. Class IV is common for metal to metal seated valves.

    Question
    What if I need parts for my Hi-Flow™ control valve?
    Answer
    Many Hi-Flow™ valves have been in service for 15+ years with all original parts. However, since Hi-Flow™ valves are commonly used in steam service, a severe application, some parts may wear over time. Unlike other control valves, Hi-Flow™ valves are designed with removable seat rings making repair or replacement of components an option. Although all parts are available, you will probably never need more than a seat ring, plug assembly, and stem packing to have a valve that is like new.
