F Series
combine excellent freeze protection and fluid temperature
control with amazing economy. You get maximum performance
at a minimum price.
Each
type F valve has unique design features that give it
special advantages in specific applications. By matching
the performance advantages of the valves to your specific
requirements, you can eliminate costly freeze damage,
reduce the waste and cost of seasonally opened block
valves, protect personnel from accidental scalding at
emergency shower and eyewash stations, provide increased
efficiencies in cooling water control and satisfy other
temperature-related flow requirements unique to your
plant facilities.
DESIGN
FEATURES
Ogontz F Series
valves are fully self-contained, temperature-actuated
devices that employ a precision, thermal actuator for
reliable operation. Each valve type includes the
following features:
- Fail-safe--(direct
acting valve opens)
- Self-contained
solid/liquid thermal actuator
- Requires
no external power or remote signal
- In-line
serviceability
- Insensitivity
to line pressure
- High
repeatability--No set point drift
- Temperature
set points from 35°F to 250°F
- Available
in line sizes from 1/2" to 2"
- 100%
factory tested
Typical
Applications
Freeze
Protection of a Condensate System
Installed
on a condensate receiver, the Type F valve provides
positive freeze protection by draining the condensate
system when fluid temperature approaches a preset,
critical temperature.
Winterization
of Exposed Overhead Pipe
When
the fluid temperature or air temperature around an
exposed water line drops toward the freezing point, the AF valve
automatically bleeds the system before the fluid can
freeze or before discharge freeze-up can become a
problem, due to a sudden drop in air temperature. The F valve can be
used for sensing water temperature only.
Freeze and
Scald Protection for an Emergency Shower
Installation
of FP and FPR valves
(direct and reverse acting) provides both freeze and
scald protection for emergency showers ( shown ) and eye
wash stations. The FDA is designed
specifically for scald protection for wash down stations.
Temperature
Control on a Water-cooled Air Compressor
A
reverse-acting FR valve
installed on a water-cooled device maintains optimum
operating temperature by controlling cooling water
discharge at a preset temperature, (e.g. controlled
discharge between 170°F and 180°F ).
