Cryogenic pressure regulating valve

Cryogenic pressure regulating valve is used for self-pressurization, when every bit of LNG is used in the tank, the pressure in the tank will be reduced, in order to maintain a certain pressure in the tank, when the pressure in the tank is reduced to a value, the pressure regulating valve will be opened, and the LNG will enter into the pressure booster through the pressure regulating valve, and the LNG will enter into the gas-phase space of the tank through the return pipe after vaporization to make the pressure rise. It is a kind of regulating valve used in low temperature and deep cold occasion. It is suitable for the regulation of the medium under -60～-250℃ low temperature strong state.
