Bellows type, Cryogenic Liquids and In-line
MC 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 LO2, LN2, LAr and LNG.
As bellows are used instead of diaphragm, Cv value of regulator is much bigger than the others.
