There is no available BTU rating on this part but this valve is rated for 15 PSI.
The valve is 3/4", 15psi setpoint and 407PPH.
Installing a lower pressure will always keep the system leaking boiler system working pressure is 12 to 15 PSI. Install a new 30 PSI PRV and replace the expansion tank. the bladder is probably blown. Gilbert Pond Pond's Plumbing & Heating (Idaho)
Make sure it is installed in the correct orientation. I had a dripping one, replaced it, still dripped. Looked at instructions and found it had to be vertical I believe, but was put in horizontal. Double check instructions for correct orientation and re-plumb if necessary. Kevin Zaitz
