1-LDC—A See-Thru Body So You’ll Know When It’s Working
Benefits You Can See

Reduced maintenance

Efficient operation

Stainless steel internals mean
corrosion resistance and reduced
maintenance.

Simple ball float mechanism
discharges only when liquid is
present so it doesn’t waste air.

Positive seating

An inside look

Free-floating valve mechanism
assures positive seating so it
prevents air loss. There are no
fixed pivots to wear or create
friction, and wear points are
heavily reinforced for long life.

See-thru body means you can
observe changing conditions
as they occur. See a problem
in the making—instead of
having to deal with it after
the fact.

In-line repairability

Corrosion resistance

Liquid Drainers

In-line connections and
an O-ring seal make for
quick, easy repairs without
dismantling piping. Just
unscrew and remove the body
for maintenance.

Long-lasting polysulfone
body and reinforced nylon cap
weigh less than 20% of cast
iron liquid drain traps. Rugged
polysulfone resists corrosion
and provides long, trouble-free
service life.

Reduced need for
cleaning

Recessed dirt pocket gives dirt
a place to accumulate away
from the valve seat. Valve seat
is 1-1/4" above the dirt pocket.
Compared to other ball float
drain traps, the Armstrong 1-LDC
reduces dirt fouling and needs
less frequent cleaning.

Simplified installation

Optional horizontal or vertical inlet
with horizontal outlet eliminates
the need for extra fittings. Makes
installation in existing systems easier.
Vertical inlet is 3/4" to accommodate
air venting. Requires no electricity.

NOTE: The Armstrong 1-LDC is not recommended for extremely dirty systems or those with heavy
oil carryover. The drain trap should not be used in an environment where there are high levels of
ketones or chlorinated or aromatic hydrocarbons.
