Features:

  • Relief pressure adjustable from 0 to 100 psi
  • 1/4" male NPT threaded inlet connection
  • Brass construction and stainless steel spring for corrosion resistance
  • Silicon O-ring provides leak-proof seal to within 10 percent of set pressure
  • Micrometer-style nylon knob for pressure relief adjustment
Functional and inexpensive

I bought this for homebrewing purposes (natural carbonation, fermenting under pressure, testing for keg leaks, etc.). I cut away the measurement sticker for a cleaner look because the markings are meaningless. It was accurate when testing on a pressurized keg. I filled the keg to ~10PSI, disconnected the gas, connected the spunding valve and slowly turned the dial until I heard pressure release. Then filled the keg to ~15PSI, disconnected the gas, reconnected the spunding valve and watched as pressure released until reaching ~10PSI when it stopped. Works well in my opinion.

The pressure is on

It took me a while to receive this item as it was hindered by a number of delivery issues. However once I received it I was pleased with the overall quality and operation. The one I eventually got actually had markings with numbers on it, not that I trust it to be super accurate. I just wanted a pressure valve that was easier to adjust for a casting pot and this one hasn't let me down.

THIS LITTLE CONTROL VALVE DOES A GIANT JOB.

I PUT IT ON TOP OF MY HEAT EX-CHANGER SET IT TO 10 POUNDS AND WATER CIRCULATION TO MY GREENHOUSE'S STAYS AT A LOW 10 PSI NO MATTER HOW HOT THE WATER NEEDS TO BE TO HEAT THE GREENHOUSE'S. IT WORKS GREAT!

Works Well

Easy to use. I have no problems adjusting it to what I need. Highly recommend.

Not sure how to read what PSI it's actually set ...

Not sure how to read what PSI it's actually set at, but that's my lazy fault. Works really well when used as a spunding valve. Will pick up a couple more in the near future.

Does what it's supposed to

Use this to transfer and ferment beer under pressure. Works great! Although for peace of mind I would recommend a pressure gauge since the numbers on it don't mean much, not to me at least .

Satisfied

Exactly what i needed

Simple, easy

Works like it should, I guess, LOL, has never gone off!

Five Stars

perfect for spunding valve. the numbers are meaningless but if you get a pressure gauge then its all good
