Big motorized steam valve

Art Pittaway

if a globe style valve is located in a horizontal run it will present a dam in the pipe that will hold condensate back. If it is installed that way without a trap or way to drain condensate you will have hammer. If the valve is installed close to a riser it can drain back into the main. Consider that even steam in a vapor system has velocity and will move the condensate along the piping to a point where it will have to be drained or will cause damage. Once again, it's a steam system and you have three fluids to deal with, steam, condensate and air/non-condensables. Miss one and you have problems.

Big valve...

I have a nasty feeling that I need a 3", preferably threaded, motorized steam valve (very low pressure -- so must have VERY low pressure drop!). I have 24 v control power available...

Checked State Supply; the biggest they have in motorized is 2" (Honeywell).

Any suggestions, guys?

Is it possible

to repair the existing one? What is there now? What went wrong with it?
