A blow valve is a valve installed within the range of a transport line, and is very similar to a butterfly body. At the same time, blower faucets for steam and hot oil are intended to be used as a kind of valves in lines where steam or hot oil are flowed, as mentioned above, which can have a very significant effect on the temperature and pressure level in the line. The number of models of these faucets is very limited, and usually these are standard transport lines, intended for exactly this purpose, so the number of models between which you will have to decide is not many. At the same time, the quality of the faucet, the manufacturer's brand and the technical characteristics of the faucet are definitely important.
