Reducing valves can work

我还以为你的再保险cent article, "Pressure Regulators: Simplicity May Suffice," (CE, Oct. '98, p.117), was great! I recommend this frequently in the field and a number of engineers look at me like I am a little "nutso."I have found most reducing valves have "swings" in pressure, and had to double up reducing valves to get really tight control.
