air gas ratio valve and zero governor valve are 2 different regulators. A "zero" governor supplies gas at approx atmospheric pressure("zero" psi) regardless of air pressure. A "ratio" regulator supplies gas pressure in proportioned "ratio" to the air pressure - meaning if, for example, the ratio is 1:1 and the air is being supplied at 8 iwc, then the gas from the regulator is supplied at 8 iwc. The language used in these systems is very commonly used interchangeably. Just my 2 cents after investing alot of time into the topic. Would love comments further clarifying. cheers.
I should have clarified that I absolutely love this video and will be using with my classes. I just think using zero governor and ratio regulator interchangeably is a bit confusing.
Best explanation in the whole internet. Thks a lot. So the venturi effect controls how much gas goes to the system by creating negative pressure. The question is what would happen if the fan stops. Would the gas continue to follow?
Thanks for the great comment. You’re right. If the fan stops the gas valve closes because there’s no pressure keeping it open. That’s why when you start the appliance the first thing you hear is the fan running. I hope that helps. 🙏
Just found the video after requesting it, brilliant video Thank you very much

Good video, illustrations and editing. Keep up the good work.
Thanks for the encouragement. I’m glad you enjoy the videos. 🙏
Thanks so much. I now feel I actually understand this key part of a boiler now.
Carefully explained and great slides. Thanks
Perfect Very clean explanation...Thanks a Lot!!!
Hi would you be able to do a vid on how a multifuctional valve works and electrical overheat stat thanks.
Hi Ruman. I’ll get onto this today and with any luck will have a video up by the weekend. Thanks for subscribing. 🙏
Hi Ruman, the video you asked for about multifunction valves is now live. I hope it helps. Cheers
Such a useful video. Thank you so much.👍👍👍👍
