What is the accuracy?

Asked by: Wolfdog
Accuracy is pretty hard to define in a manually adjustable regulator. I suspect the Type 91&rsquo;s is around 4%, while the Type 92&rsquo;s is about 3.5%.

Can this be used in a water regulation application? I need to regulate a small amount of water flow to 1-4psi 5psi max.

Asked by: Buddy
These regulators are design for use with AIR only. They regulator pressure by bleeding off excess pressure. Water would be spraying out of the bleed port on the regulator.
