I wonder if Paul is still active in the business. I believe he's got 15-20 yrs on me (57). I do see those trucks in Manhattan still. Mad Dog

Yes, he is @Mad Dog_2. See below.

I had always wondered about the orifice trick. Does it really work? Can it be used on a commercial building? Thanks

Elegant simplicity in the mechanical sense, combined with a good feel for when people need help. THIS makes a great story when woven together by a master storyteller. 😇

Yours, Larry

The orifice will work anywhere you can keep the pressure controlled. In theory you could size the orifice for higher pressures and it would work there too as long as the utilization equipment has a consistent load and you could control the pressure at the higher pressure..

but the boiler water line has changed in the past 100 years…

RayW, the orifice "trick" does work. I have used it a lot in my very small service area.

There is a chart for sizing based on the pressure applied. You can install such that will deliver 80% of rad EDR. You seldom need even 80% for most rooms.

These do what an adjustable controlling inlet valve do, if never tampered with, so you know what happens to those control valves. Constantly messed with or just drift their adjustment over time.

So open all the way and only get 80% EDR or have the ability to shut off completely.

I have often removed rad trap elements and not have a problem……..as long as the pressure is left set reasonably low.
