The No.8 fixed temperature
liquid expansion thermostatic steam trap has an oil filled
element set to operate at a fixed temperature. It is one of
the simplest thermostatic traps currently available.
Under cold conditions, such
as start-up, the oil filled element is fully off its seat
allowing unrestricted removal of cold condensate, air and
other incondensables. As hot condensate enters through the
trap, the oil filled element heats up and expands, closing
the valve against the seat. The adjustment of the element
allows the temperature of the trap discharge i.e. the
temperature at which the valve opens again, to be altered
between 60°C and 100°C (140°F and 212°F) simply by turning
the adjustment nut. |
