Iron Valve Options and Accessories
Operating Nut, Position Indicator, Sprocket Rims
Square Operating Nut
The square operating nut can be substituted for the regular handwheel when an NRS (619 & 639) valve is to
be installed in an inaccessible location. It may be operated by a key or a wrench. A directional arrow
indicating "open" is cast on top of the nut. All square operating nuts have a standard 2" square which
facilitates opening and closing the valve with a square socket wrench as used by the Water Works.
Material: Cast Iron ASTM A126 Class B. Field retrofit is standard. Some factory installed versions are available.
Position Indicator
For non-rising stem (2"–12") metal seated, (not resilient wedge,) iron body gate valves. Indicates
whether it is open, partly open or closed by the position of the needle which moves as the valve is
operated. Field installed.
Ordering Information: Specify size and figure number of the valve to be fitted.
Adjustable Sprocket
The Adjustable Sprocket Rim will provide
for remote operation of gate, globe and
angle valves in high, normally out-of-
reach locations. Attaches to valve wheel
for instant valve open/close response.
Sprocket rim made from cast iron, chain
guide is malleable iron. When ordering,
specify either the sprocket and chain num-
ber, or the NIBCO
®
valve figure number
and size. The chain length must also be
specified.
Hammer-Blow Sprocket
The Adjustable Hammer-Blow Sprocket
Rim is for use with hard-to-operate gate,
globe and angle valves in overhead loca-
tions. The Hammer-Blow plate and rim
are made of tough, shock resistant ductile
iron to withstand heavy, valve releas-
ing impact. The chain guide is malleable
iron. When ordering, specify the sprocket
number, chain number and length, or the
NIBCO valve figure number, size and the
chain length.
