1824A Lubricated Plug Valves
are all iron (semi-steel)
construction. 1824A valves can be used as a manual isolaton
valve to provide a tight shut off .
Ratings:
Maximum inlet pressure: 200 psi
Temperature range: –20°F to 450°F
All 1824A valves have removable wrench handles.
CAUTION:
Some valves handles can be indexed in 45° increments, which
means handle position may not indicate plug position (open or
closed). To be sure a valve is fully closed, check that it is turned
fully clockwise to stop.
Newer style valves have handles that can be indexed only in 180°
increments, thus always indicate plug position.
In abnormally hot, dirty, or corrosive conditions, most
shutoff valves can deteriorate and fail to shut off tightly.
Frequent, periodic checking of all valves is strongly
recommended. Per NFPA 86, these valves must be lubricated
and subsequently leak tested for valve closure at least
annually.
Valve position indicator is a sleeve that rotates to cover a collar
when valve is closed, exposes collar when valve is open.

Product Overview | Lubricated Valves
How to Lubricate:
Valve should be in the open or closed
position while lubricating. Lubricant can be introduced while
the valve is under line pressure; a check valve prevents back
leakage of the line contents. If valve is equipped with buttonhead
fi tting, attach grease gun and pump the lubricant into valve until
lubricant begins to escape visibly around neck of plug. This
indicates that valve is fully lubricated. If valve is equipped with
conventional lubricant screw, remove screw from stem, insert
a stick of lubricant into the stem and force lubricant slowly

lubrication. Lubricate through these fi ttings as well as the stem.
Operation:
Valve opens in a counterclockwise direction, closes
Maintenance:
To ensure tightness, maximum life, and ease of
operation, the valve should be thoroughly lubricated at regular
intervals. Your maintenance schedule for the valve will depend
on service handled by the valve and frequency of operation. You
can use sealant handgun R400-6210 to lubricate the valve.
