Kingston KSV10 Series Brass ASME-Code Low Profile Safety Valve, 150 psi Set Pressure, 1/4" NPT Male

Starts seeping air around 145 does blow off at 150 running my compressor at 140 to keep it from hissing air.update is starting to leak air at 135 psi and is blowing off intermediately have turned my compressor down to 130 psi to keep it from blowing off.I have checked with multiple gauges they all read the same that it's blowing off earlier than before.

Would order this again, IF I ever need to replace it. Hopefully I'll need a new compressor before that. This was an exact replacement for the one I had. Anybody could replace theirs if needed.

This item is machined well and fits as it should. I have not been able to test it's relief setting but it does reseat and seal at about 125psi if manually opened.

Set point on this one is accurate.

I used this valve to replace an old bulky valve. It is small and versatile for cramped areas. Works just fine

Perfect replacement!

Got here very quickly works great totally satisfied. Will order another one soon as a backup. I recommend this vendor and always use safety valve for safety sake.

Purchased with the Powermate 034-0197RP Pressure Switch for my 20 gal garage compressor. Not really too much to review here, but the product came as advertised and works. Thanks.

Worked great. Happy with it.

Works perfectly and would buy another. Worked great on my 14 gal compressor, wanted more psi. The stock relief was to low 80 psi.

The valve is worth replacing when purchasing a new pressure switch , the old valve spring and o ring may be worn out leaking air.

This dog whistle works wonders! When I blow through it, you can't hear anything (because only dogs hear the pitch). I take it to the beach, the park, around town. People love it. I think they love it because it's made out of brass, and isn't cheap looking as some other dog whistles.
