1" NPT Horizontal Check Valve, Brass Non Return Swing Check Valve to Prevent Water Backflow, Level One Way Counterflow Valve to Prevent the Medium Backflow for Oil Water Gas Air（1", DN25）

Seems like decent quality and threads are good.

Solid construction, well-machined, priced right. Works as described/expected. My application is in a low pressure hydronic loop to prevent backflow.

I needed this to repair an issue with my rural well. The old valve was leaking and a replacement was not available at the Blue or Orange stores locally.The casting/machining and threads are very clean. The valve works properly and I have no concerns about it's longevity... Great price too!

Muy bueno gracias

works good

Got it installed and working as it should. Great value for price.

Great and in time

This is a cheap check valve, the original one held water pressure no problem, this one will not hold 60 psi of water pressure. It continuously leaks past the check valve…
