Hansen HS6 Operating instructions

INTRODUCTION
This flanged, industrial refrigeration duty solenoid
valve is very simple and compact but rugged in
construction. Body is plated steel alloy with a
direct lifting stainless steel plunger that contains
a teflon seat that closes on a stainless steel
orifice. When electrically energized, seat opens
wide; when de-energized, it closes to stop flow
in the arrow direction on the valve body.
APPLICATIONS
This small, direct lifting valve is used primarily
as a pilot for various larger gas-powered or
liquid powered main valves, as a remote pilot
for back pressure regulators or other devices,
or as a liquid stop valve for expansion valves,
float valves, or as a general purpose pilot line for
ammonia, R22, R134a, CO2 and other approved
refrigerants or oil.

ADVANTAGES
Power saving, low-wattage encapsulated coil; teflon
seat; stainless steel trim; spring-closing; double-seal
manual opening stem. One standard encapsulated
coil fits all Hansen valves.
INSTALLATION
Match arrow on body with system flow direction.
Protect interior of valve from dirt during installation;
normally use close-coupled inlet strainer. Allow 2.25”
(57 mm) above valve for coil removal, 1” (25 mm) below
for seal cap removal, and 3” (76 mm) below strainer
for screen removal. If a pressure reversal can occur,
as during hot gas defrost with liquid recirculation,
use a check valve on the outlet side of the HS6. For
proper flange gasket sealing, care must be taken when
threading or welding to assure flanges are parallel to
each other and perpendicular to pipe. Also, gaskets
should be lightly oiled and all bolts must be tightened
evenly.
ELECTRICAL
The coil draws 16 watts and will operate properly
between 85% and 110% of rated voltage (24V coil
draws 19 watts). Standard coil connection is a 1/2”
fitting (NPSM) for conduit, with two 18” wire leads and
ground wire. Coils with DIN plug or 1/2” NPSM quick
disconnect plug are available. Contact the factory.
All coils are totally encapsulated and meet NEMA 3R
(rainproof) and NEMA 4 (splashproof, approx. IP65)
requirements. The coil should only be energized
while on the solenoid tube. Otherwise, immediate coil
burnout may occur. To avoid bending the solenoid
tube, remove the coil from valve before connecting
any electrical conduit. Pilot lights are available.

SERVICE AND MAINTENANCE
Failure to open: Wrong voltage coil; low
line voltage; controlling switch or thermostat
not contacting; coil is burned-out; inlet/outlet
pressure differential too high; plunger is jammed
closed with dirt.
Failure to close: Controlling switch or thermostat
not opening contacts; manual opening stem is
turned in; dirt under seat; eroded seat parts;
plunger is jammed upward by dirt.
Before opening the valve for service, be sure it
is isolated from the system and all refrigerant
is removed. Disconnect electrical power from
coil. Remove the coil by unscrewing the coil
knob. Loosen the four solenoid tube screws
and break gasket seal, proceeding cautiously
to avoid any refrigerant still remaining inside the
valve. Remove the tube screws to separate the
solenoid tube from the body.
Check face of teflon seat in plunger, plunger
spring, and seat orifice in body. Clean, polish
or replace parts as necessary. Always replace
the solenoid tube when replacing the plunger.
These are wear parts and must be inspected
as part of a routine maintenance program. The
seat orifice is integral with the body. Install new
solenoid tube gasket and oil lightly. Reassemble
tube to body with four screws. Factory torque is
2 ft-lbs (2.8 Nm). Carefully check the valve for
leaks before restoring to service.
CAUTION
Hansen valves are for refrigeration systems
only. These instructions must be completely
read and understood before selecting, using or
servicing valves. Only knowledgeable, trained
refrigeration mechanics should install, operate,
or service these valves. Stated temperature and
pressure limits should not be exceeded. Solenoid
tubes should not be removed from valves unless
system has been evacuated to zero pressure.
See also the Safety Precautions in the current
List Price and the Safety Precautions Sheet
supplied with product. Escaping refrigerant
might cause personal injury, particularly to the
eyes and lungs.
WARRANTY
All Hansen products, except electronics,
are guaranteed against defective materials
or workmanship for one year F.O.B. factory.
Electronics are guaranteed against defective
materials or workmanship for 90 days F.O.B.
factory. No consequential damages or field labor
is included.
