Fluid Handling Technology Flashcards
The operation of a thermostatic steam trap depends upon what?
The difference in temperature between the condensate and the steam
In a thermostatic steam trap, the bellows is also known as the…
Element
T/F: The bellows of a thermostatic steam trap contains a volatile fluid which boils by the heat from the hot condensate that surrounds the bellows.
F: The fluid boils by the heat from the steam, not condensate.
Three components of the inverted bucket steam trap are:
Strainer, inverted bucket and valve lever.
T/F: The bonnet on a globe valve is located above the packing nut.
False

What are the two styles of butterfly valve bodies?
Lug and Wafer
T/F: The butterfly valve is relatively lightweight.
True
An erratic pressure downstream of a steam pressure control valve may be caused by:
Control valve hunting.
