2" NPT Female WOG1000 Check Valve,Spring Loaded In-line Low Cracking Pressure,Stainless Steel SS316 CF8M

Fast shipping high quality and works just as it should.

Does what it is supposed to do.

I bought this because from the review it seemed like a well made product. On inspection it also appeared well made. I was using this on a pool pump. However, I could never get it to stop leaking. I replaced both parts that screwed into the threads, I used different sealants, but could not stop the small leaks at both threads. This was only working at a pressure of 15 psi. I finally replaced it and upon disassembly of the parts attached and looking carefully at the check valve, it appeared that the threads had not been cut deep enough, which is why no sealant helped. I had tried teflon tape, teflon sealant used on high pressure fittings and even Tru-Blu by Rectorseal. Since I was past the return date, I felt as though I should warn others of the potential problem. Perhaps mine was the only one with a problem. It appears to be high quality, but I could never solve the problem of the leaks. Replaced it with a plastic checkvalve and the problem was solved.

The media could not be loaded. I used this check valve on a submersible pump in a river to feed my sprinkler irrigation. Works as it should without restricting the water flow as displayed in the video.

These do not hold with only 35 psi. Unfortunately one is installed 270' at the bottom of my well. I don't believe that they are worth the scrap metal that they are made from.

I opened the check valve, there is no rubber seal of any kind, the machined surface was flat, the 316 Ss is actually 304 ss, some rust present after exposed to acid, non magnetic, the spring rate was too high requiring double the pressure to be compressed. For 20$ is what you get. It does not hold water it drip every 1.3 seconds one drop. I drilled two holes and tapped in flat area and added a SS washer with a 2” rubber seal and 2 screws for 6$ and seals perfectly now. If you don’t want to reinvent the wheel don’t buy this.

On first glance the valve looks great! However a look inside tells a different story. The description mentions a FTPE seal which the valve I received did not possess. It does have a moving, spring loaded machined disc that rests against an un-machined surface when the valve is closed. It would be impossible for this valve to hold water pressure. The best it can do is restrict water flow.
