Overhead Wheel & Chain Assembly
Overhead wheel and chain assembly allows
operation of a manual reset valve in an otherwise
inaccessible overhead location. A wheel is mounted
onto the handle of the valve. The attached chain is
weighted on one end and has a paddle handgrip on
the other.
Once the valve is electrically energized, pulling
down on the paddle will open normally closed ver-
sions or close normally open versions.
Maxon valve's free-handle design permits valve to
trip to its rest position on any power interruption.
Wheel and chain assembly includes a length of
chain to position the paddle handgrip slightly below
pipe centerline. A standard length of 7 feet of chain is
included with CP and larger valve sizes and 5 feet is
included with all other valves. Extra chain (in one foot
increments) may be specified to fit your specific
location.
NOTE: Overhead wheel & chain can only be mounted
on swinging gate valves with the top assembly
position TO.
