Hey i received this valve body after it had been handed down many hands but never actually ran. My question is how can i tell if its a constant presure of variable.?
 
I have a fmvb constant pressure from FP.
It still has the TV lever, but they include a bracket that sets the lever stationary at about the 3/4 back position.
