and is more particularly concerned with indicat
ing means for use on valves or the like of the
non-rising stem type to disclose the position of
the valve closure member with respect to the
body seat in the valve housing, and has for an
object the provision of an indicating means which
is relatively inexpensive in construction, reliable
in operation, and which will not readily get out
of order.
This invention further contemplates the provi

In operation, rotational movement of the hand
wheel 9 causes axial movement of the pointer I2
between the full open position and the full closed
position marked at 3| `and 32, respectively, on the
indicator plate Il. Suitable intermediate grad

to indi-cate intermediate positions of the Valve
closure member (not shown).
In repacking a valve equipped with an indicator
device as shown, the handwheel is removed from
