| All Clark-Reliance
water columns and components are designed and manufactured in
total compliance with ASME Boiler Code provisions. Of special
importance, all steel water columns are welded according to
specific ASME code provisions and procedures. Water columns
and components such as gages and valves are hydrostatically
tested to 150% of design pressure.
Today, Clark-Reliance continues as the foremost name in water
column technology and manufacture. Current, advanced products
are modern-day versions of columns and trim pioneered by the
Reliance Gauge Column Co., America's oldest and most respected
exclusive boiler trim manufacturer. |

| Float
Type |
- Cast Iron Column: 0 - 250 psi
- Steel Column: 250 To 900 psi
Float type water column models are
individually rated at pressures from 0 to 900 PSI. All float
type columns are designed to feature the Clark-Reliance audible
safety alarm mechanism.
 At
designated water levels, floats automatically trigger the
alarm. The shrill tone of a brass whistle signals predetermined
high or low water levels, acting to within one quarter inch
level variations. The action is direct and extraordinarily
reliable.
Alarm components sit high in the column,
away from corrosive agents and scale. Design simplicity eliminates
periodic alarm adjustment and scheduled alarm maintenance.
Alarms can respond to water levels high and low, high only,
or low only. Additional float actuated electric alarms can
be operated at remote locations by installing a Clark-Reliance
LEVALARM© accessory. Columns without alarms are available.
Float type columns are available for
all types of boilers. Models offer a variety of water gage
valve connection centers and a selection of many steam and
water centers. All models are products of precision manufacturing
standards and employ high quality materials throughout. |
