CT150 Series Steam Trap.
INTRODUCTION
Scope of the manual
This manual provides instructions for
operation, installation and parts ordering for
the CT150 Series.
Product Description
A steam trap is an automatic valve which
discharges condensate, undesirable air and
non condensible from a system while trapping,
or holding in, steam.
Thermostatic steam traps operate in direct
response to the temperature within the trap.
The CT150 Series are thermostatically actuated
and maintenance free. Actuator is single
piece, fail open design consisting in 1.2 in.
(12.7 mm) diameter, welded 316L stainless
steel plates. Trap is constructed entirely of
316L stainless steel components with wetted
body surfaces finished to 20 μ in. Ra or better.
Trap is self draining when installed vertically
in piping systems. It has a tube or universal
ferruled connections. Ferruled connections are
Tri-clamps compatible and designed to fit both
½ and ¾ in. (12.7 and 19.1 mm) service.
SPECIFICATIONS
The specifications section gives some
general specifications for the CT150 Series
Thermostatic Steam Traps. The nameplates
give detailed information for a specific steam
trap as built in the factory.

INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
PRINCIPLE OF OPERATION
Thermal actuator is filled at its free length with
a liquid having a lower boiling point than water.
On start-up, valve is normally open to discharge
air, non-condensibles and condensate.
When steam enters trap, thermal actuator
fill vaporizes to a pressure higher than line
pressure. This forces valve into seat orifice to
prevent any further flow.
As condensate collects, it takes heat from
thermal actuator, lowering internal pressure.
Line pressure will then compress thermal
actuator to open valve and discharge
condensate. Valve opening automatically
adjusts to load conditions from minimum on
very light loads to full lift at maximum load.
• Best Air Handling Capacity — Fast start up
and operation.
• Fast Response — Quickly adjusts to
condensate load or temperature changes.
• One Size Suits Most Services — Universal
ferruled end connection fits both ½ and ¾ in.
(12.7 and 19.1 mm) piping.
WARNING
Personal injury or system damage may result if
this steam trap is installed, without appropiate
overpressure protection, where service conditions
could exceed the limits given in the Specifications
section and/or steam trap nameplate.
Additionally, physical damage to the steam trap
may result in personal injury or property damage
due to escaping of accumulated gas. To avoid
such injury and damage, install the steam trap in
a safe location.
All pressure equipment should be installed in
a non-seismic areal should not be exposed to
fire; and should be protected from thunderbolt
(lightning) striles.
INSTALLATION
1. Before installing trap, blow all dirt and scale
from apparatus and piping.
2. Install trap with arrow on body in flow line
as close as possible to apparatus with
strainer and valve upstream of trap.
3. Pitch all drain lines toward trap.
NOTE
Approved practice is to install separate traps on
each piece of apparatus to be drained. Steam
supplied to inlets of several units may be of uniform
pressure, but invariably there is a differential at the
outlets. Although this differential may be small, unit
discharging highest pressure will control the action of
trap, while other units become air-bound and water
logged. Piping upstream and downstream of trap
should be at least equal to or one size larger than
trap connection.
4. Record the location of the trap for
maintenance accessibility.
MAINTENANCE
The CT150 Series Thermostatic Steam Traps
are sealed units making it maintenance free. It
is composed of corrosion resistant stainless
steel components with welded construction to
prevent damage to actuator. No bolts, gaskets
or adjustments are necessary.
