Hi PD’s - …..Matt asks ….[have left the original message to reference Matt’s questions ]  
   
I'm looking for more information on automatic steam pressure regulators and propane/butane gas regulators  
   
Both ANTON & JMC [via our PD links] manufacture & supply gas regulators…[one of our members…’ENGINE MAN’ steered me in the right direction a year or so ago] I chose the ANTON V71 as it appeared simple – as per the attachments which addresses your point 1) it also has certain functionality toward point 2)  
   
ANTON also have an additional unit that covers your point 3), however this is really designed as a fail safe on “low steam =  no water = no flame”…model engineers do not have leaky GAZ systems……………[we hope]  
   
The V71 is designed to provide the reverse of point 4) in that it is load sensitive & thus compensates or regulates  
   
I have attached a schematic from JMC which is self explanatory  
   
If you GOOGLE on ‘Daniel Bourard’ you will find manufacturing Drawings for gas regulators…..[you will also find DB via links from JMC or ANTON]….he is an accomplished French model engineer….but please read the associated text as one of his GAZ regulators did not work all that well  
   
People will still talk about the CHEDDAR brand  ‘ABC’ [automatic boiler control] system which covered points 1) > 4) inclusive, however [sadly] this Company no longer exists.....................

I'm looking for more information on automatic steam pressure regulators and propane/butane gas regulators. I just bought Stan Bray's book which briefly discusses these devices. Now I want more detail.
 
 It appears that there are several things one might want such a device to do:
 
 *1) You could regulate gas pressure based on steam pressure, presumably turning the flame up when the steam pressure drops.
 
 *2) You might turns the main gas jet completely off and on; relying on a pilot light in the latter case.
 
 *3) You might shut the gas off permanently if the steam pressure suddenly drops to zero. This way a pressure leak wouldn't cause your boat to catch fire.
 
 *4) Perhaps the most obvious use would be to deliver constant steam pressure to your engine, or constant gas pressure to your burner.
 
 *5) Are these devices commonly used? What's the most common plumbing arrangement?
 
 *6) Is there a manufacturer's web site with more information?
 
 *7) Are there plans and instructions available for making and testing these devices?

Sorry Matt..... my fault.... - bloody French....ANTON is listed as Fabrice BRETAGNE in our PD links

& Mortiz.... I had not read you previous explanation/comment  on the ABC Cheddar unit..... my fault....
