QiiMii Sanitary Stainless Steel 304 Tri Clamp Butterfly Valve with Trigger Handle and EPDM Seal (1.5 inch (1 pack))

I wanted to add a couple more butterfly valves to my conical, but I didn't want to spend a ton. These fit the bill nicely. I'm impressed with their heft and quality. The handles are polished and they seal well. They take a little more force to open, but I was more concerned with if they would hold. I haven't tried fermenting under pressure with them yet, but they are doing fine for the first brew.

Not usually writing reviews but after unwrapping the amazingly well packaged valve and being in awe with the quality of manufacturing and the ability to swing the handle at 180 degrees I can only advise anyone on the verge of buying this product to do so. The price is really affordable compared to other inferior products. Thank you.

Very nice quality. Works great. As good as anything from the big brands.

Overall, they are good for the money. Second time ordering them. They do work as advertised. For the money, they work fine in a craft brewery.

high quality and quick with the delivery.

Worked great as an upgrade to my hash washer

I've used these three times since I received them and love them. I will be upgrading my other three fermenters with these valves. Follow up 2/8/2020 since my original purchase I have upgraded my other three fermenters to these butterfly valves. That is a total of 8 valves. I have experienced zero negatives. I do not take the valves apart between batches. I just clean with PBW before and after each use. I have however taken apart each valve after a few batches to see if anything was getting in between the seals that could cause an infection. I found nothing. Squeaky clean as they should be. After two years, my five-star rating still stands. I have brewed over 30 batches with no issues.

Nice feel with good quality but the action to overcome the friction to start to open is way to much and makes this product difficult to use.
