Hansen HS2, HS2F Specifications, Applications, Service Instructions & Parts

HS2 Solenoid Valve

This threaded end industrial refrigeration duty
solenoid valve is very simple and compact but
rugged in construction. Body is plated steel alloy.
The direct lifting stainless steel plunger contains a
Teflon seat which closes on a stainless steel orifice.
When electrically energized, valve opens wide; when
de-energized, flow stops in the direction of the arrow
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
disc seat; stainless steel trim; spring-closing. One
standard coil fits all Hansen valves. The valve can be
installed in vertical lines.

INSTALLATION, THREADED
CONNECTION

Match the arrow on the body with the system flow
direction. Protect the interior of the valve from dir t
during installation. Check mating pipe threads for
cleanliness and accuracy before installing. Use a
small quantity of pipe dope on pipe threads. Use a
flat jaw wrench on the body close to the pipe, being
careful not to damage the pipe threads with pipe
wrench jaws. Allow 2.25" (57 mm) above the valve
for coil removal.

ELECTRICAL

The coil draws 16 watts and will operate properly
between 85% and 110% of the rated voltage (24V coil
draws 19 watts). Standard coil connection is a 1/2"
fi t t i ng (NPS M ) for c o nduit, w ith two 18" wir e leads p l us
gr o und w ire. Coils with DIN p lug o r 1/2" N PSM q uick
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 the valve before connecting
any electrical conduit. Pilot lights are available.
