| "Rectangular Port" - Homestead® Lubricated
Plug Valves have rectangular shaped ports through the plug
and body. The area of the port is either equal to 100% of
the area of standard pipe, or restricted (standard opening);
but in either case it is clearly marked for the various figure
numbers.
"100% Area" (Full Port) -
means the area through the valve is equal to or greater than
the area of standard pipe.
"Standard Opening" - means
that the area through the valve is less than the area of
standard pipe, and therefore these valves should be used
only where restriction of flow is unimportant.
"Round Port" - means that
the valve has a full round opening through the plug and body,
of the same size and area as standard pipe.
"Diamond Port" - means the
opening through the plug is diamond shaped. All diamond port
valves are restricted flow type.
"WOG" - Water, oil, gas (Cold
working pressure)
"SWP" - Steam Working Pressure
"ANSI" - American National
Standards Institute
"CWP" - Cold Working Pressure
