Bermad 420 Pressure Reducing Valve - How to Demonstration

[@andresa.g.6668]

Very interesting video, I would like to know if the Bermad 400 SERIES always comes with a spring, or is there any model which only operates with the diaphragm.
Thanks in advance.

Please I repeat: "Could you make a demonstration about the regulation at 0 flow? for 120 modele too and with the same three way pilot? please."
