valves
 

can anyone tell me the difference between a dumpvalve and a blowoff valve?

sedge:notworthy

Just two different ways of referring to the same thing.

thanx splitpin, thought that was the case

sedge:lol:

As above, although some people use BOV to mean a Vent To Atmosphere, (VTA) valve, which is NOT dumpvalve of choice on a Scoob.
