Bellows type, Cryogenic Liquids and In-line
“Corrosive Gas Pressure Regulator” is designed to control pressure on both cryogenic liquid system and in-line.
This is used extensively in bulk storage tanks, portable liquid cylinders, vaporizer and pipelines for NH3, LC₂H₄ and LCL₂.
As bellows are used instead of diaphragm, Cv value of regulator is much bigger than the others.
