I. DESCRIPTION AND SCOPE
Model C-CS is a pressure reducing regulator used to control down stream (outlet or P
sizes are 3/4" (DN20), 1" (DN25), 1-1/2" (DN40), 2" (DN50) and 3" (DN80) with Tri-Clamp
regulator is primarily designed for steam service at tem per a tures equal to or less than 366°F (185°C); this cor re sponds
to 150 psig (10.3 Barg) sat u rat ed steam; however, the unit may also be used for clean gaseous or liquid applications.
II. INSTALLATION
1. An inlet block valve should always be in stalled.
2. If service application is continuous such that
shutdown is not readily accomplished, it is
recommended that inlet and outlet block valves
and a manual bypass valve be in stalled.
3. An outlet pressure gauge should be lo cat ed
ap prox i mate ly ten pipe diameters down stream
and within sight.
4. All installations should include a down stream
re lief device if the inlet pressure could exceed
the pressure rating of any down stream
equip ment.
5. Flow Direction: Install so the flow enters
through the bottom connection and exits the
side connection.
6. Install in a well drained pipe, properly trapped,
with spring chamber (2) in the vertical position
to allow for proper drain ing.
III. PRINCIPLE OF OPERATION
1. Movement occurs as pressure variations
reg is ter on the diaphragm. The registering
pres sure is the outlet, P
pressure. The range spring opposes di a phragm
move ment. As the outlet pressure drops, the
range spring pushes the diaphragm down,

7. For insulated piping systems, the regulator
should not be insulated.
Installation of adequate overpressure protection
is recommended to protect the regulator from
overpressure and all downstream equipment from
damage in the event of regulator failure.
Do not apply spring load or operate regulator with
hitch pin (21) removed from top of guide post (27 ).
