INSTALLATION DIMENSIONS (inches)
SERVICE AND MAINTENANCE
Hansen gauge valves require practically no service
or maintenance due to the combination of polished
stainless steel stem and reliable O-ring stem seal plus
graphite composite packing. However, if tightening
is ever needed, use a 3/8" open end wrench or an 8"
adjustable wrench. Extrusion of some black graphite
packing material along the stem is normal.
If the O-ring or the adjustable packing ever needs
replacement as evidenced by refrigerant or oil leakage at
the stem, isolate valve from the system and evacuate to
zero pressure in accordance with appropriate practices.
Seal caps [1/4" (P/N 50–1071), 3/8"–1/2" (P/N 50–1036)]
or bar handles [1/4" (P/N 50–1069), 3/8" (P/N 50–1075)]
can be easily retro-fitted to valves in the field. All
bodies have seal cap threads; simply screw seal cap
with O-ring onto these threads. Bar handle kit comes
with pin partially installed in handle Place handle on
stem and turn clockwise to close valve. Begin to push
pin through handle and valve stem using pliers, then
tap with hammer to finish.
CAUTION
Hansen valves are for refrigeration systems only. Read
these instructions completely before selecting, using,
or servicing these valves. Only knowledgeable, trained
refrigeration technicians should install, operate, or
service these valves. Stated temperature and pressure
limits should not be exceeded. Bonnets should not
be removed from valves unless the system has been
evacuated to zero pressure. See also Safety Precautions
in the current List Price Schedule and the Safety
Precautions Sheet supplied with the product.
WARRANTY
Hansen valves are guaranteed against defective materials
or workmanship for one year F.O.B. our factory. No
consequential damages or field labor is included.

TRANSDUCER VALVE
The H9490 Transducer Valve can be installed wherever
pressure monitoring is desired. Turn stem all the way
in (clockwise) and seat to isolate pressure from both
gauge and transducer ports. Turn stem all the way out
(counter-clockwise) and seat to isolate pressure from
the gauge port. With stem in middle position, both
ports are active.
