^^^^^^^^^^^^^^^^^^^^^
My evidence is simple science.  Conservation of energy.  When you pass a gas
through a device to lower its pressure, there are three ways the energy can
go:  1.)  It can do work by running a motor or pushing a piston,  2..)  It
can accelerate through a nozzle, turning the stored pressure energy into
kinetic energy (the gas accelerates in the nozzle, 3.) The energy is turned
into heat in the throttling process.  Since a regulator does not employ
process 1.) or 2.), it must turn the energy into heat.  QED.

In a nutshell: The operating machine (piston, motor, whatever) uses
air-------pressure drops below your set level-------a poppet style
valve
opens and allows air pressure to enter the machine----the pressure
rises in the machine to your set point-----air stops flowing into the
machine----now repeat this rapidly and you have a modern pressure
regulator.

No air blowing off
No "hot" regulator
Understand?
Unless??? Are you a quibbler?
