Dunham Oriflex Valve

Late 1930's Dunham catalog shows something call a Oriflex Type 175 Valve, designed for VariVac. It seems to be an infinitely adjustable rad valve. Anyone know if this Valve has a currently produced cousin? Any info would be great...thanks!

    Mepco...Formerly Dunham has them as does Marsh. I think there may be more too.

    I just found Oriflex valves on a mid 60s vacuum system.
    Mepco sold some of their lines (vacuum) to Vent-rite.
    Neither have this valve still.
