Is this pgv diaphragm for a 1” zone valve

Yes. I even got it to work on a 3/4" valve

I am searching for a hunter valve bonnet hpv replacement? Can you tell me where I can find one?!?!

You'll need to purchase the complete / entire valve --- can't buy only the top bonnet. Try locating a used one by posting your bonnet request on Craig's list or some social network site (e.g., Nextdoor) and solicit for a used bonnet - specific make and model. Call a sprinkler repair company and they may have a used part :>)

Does it fit in the 2 inch valve?

I doubt it. Do a search on Amazon for : 2 inch sprinkler valve diaphragm hunter. That will pull up the correct diaphragm.

In viewing the video for determining the cause of the valve not working, no mention was made of a diaphragm problem. Shouldn't this be addressed?"

There is a plastic ring in these diaphragms and they will crack after a period of time and then cause the valve to function improperly. Happened twice to us in 6 years.

Replacement worked perfectly, installation was a bit challenging.

Good quality diaphragm for sprinkler valve, original manufacture’s equipment. It was a bit of a challenge to get down into the sprinkler well and remove the very tight screws from the valve. Of course, water leaked in from the sprinkler pipe and I had to clear that out as well as some debris that got into the valve. But, I did get the job done and it works great. No more leakage!

Great replacement but inspect before installing

This is a perfect fit, reasonably priced replacement for your sprinkler system valves Easy to install. It would have been a 5 star product for me except that one of the units was torn right out of the box Didn't find out until I had installed it and took a while to.figure out what was causing a steady stream of water to the sprinkler heads even when the system was in the "Off" position
