3. Packing Adjustment
a. If stem leakage occurs, tighten packing to compensate for wear. The
packing nut (under handle) should be tightened in 1/8- to 1/4-turn
increments, just enough to stop leakage. This can be done with any
appropriate flat-jawed wrench. Packing nut shall not be tightened in
excess of torque specified in Table 1.
b. Please contact NIBCO Customer Service or reference latest applicable
NIBCO Price Sheet for available replacement parts.
VIII. HANDLE OPTIONS
1. Extended Lever Handle with Memory Stop (EL)
a. The Extended Lever Handle is designed to allow valve operation on
insulated chilled and hot water lines, accommodating up to 2” of insulation.
Memory Stop functionality is included.
b. Installation
i. Remove handle nut and lever handle to access bare stem.
ii. Place extended lever handle memory stop plate over stem and
install provided barrel nut (follow handle nut torque for valve size in
Table 1).
NOTE: If handle or lock plate binds on packing nut when rotated,
tighten packing nut 1/8-turn and retry. Repeat until handle
and memory stop plate travel freely, not to exceed 1/2-turn.
iii. Loosen (do not remove) the screw and lock nut holding memory
stop plate to bottom of extended lever handle.
iv. Slide the memory stop plate against the valve handle stop.
v. Tighten the screw and lock nut. The valve can now be closed and
then reopened to the set position.
2. Locking Lever Handle (LL)
a. The locking lever handle is a feature that allows the valve to be locked in
the closed or open position.
b. Installation
i. Remove handle nut and lever handle to access bare stem.
ii. Place lock plate over stem (“TOP” facing up, round hole over stem,
half-round cutout touching handle stop) and reinstall handle and
handle nut (see Table 1 for wrench size and torque).
NOTE: If handle or lock plate binds on packing nut when rotated,
tighten packing nut 1/8-turn and retry. Repeat until handle
and lock plate travel freely, not to exceed 1/2-turn.
