Doesn't close once opened. Set for 125, opening at 90 psi. Not worth the price

When I got the part it was not assembled - the valve seat was loose in the box. The housing was staked around the knob so it seems like it wasn't intended to be that way. Had to force the knob out of the housing, rebuild the valve assembly and then stake down around the knob again so it would work properly. Took me maybe 90 extra minutes to figure it all out and make it work. Would have returned it if it wasn't for the water leak... Otherwise the part works great.

I tried two of these and they both leaked out the end, just a slow drip, and seeming to have nothing to do with relieving of pressure, but just the draining of outlet line "after" they no longer were relieving pressure. So if it was facing downward it may be fine, but my application required it to send the water which exceeded the set regulation, upward. There was also a lot of "clatter" in one of them as it relieved the pressure. It could just be an O-Ring inside that's not sealing, but the adjustable end is actually held in, in such a way that it can't be removed for repair by DIYers. I need the adjustability for my application so will just try another brand.
