Abstract
A valve assembly () including a valve body () and a position-indicating knob assembly () is provided wherein the assembly () indicates three different valve positions, namely valve closed, partially opened and full open positions. The preferred assembly () includes a rotatable knob () including a viewing port () therein, together with an indicator ring () having three differently colored regions () corresponding to the different valve positions. A coupling assembly () operably couples the knob () and indicator () so that the individual colored regions () come into view through the port () when the valve body () reaches the different valve positions. The assembly () is particularly useful with valves requiring greater than one revolution between valve closed and valve full open positions, such as valves used in conjunction with emergency oxygen cylinders on aircraft.
