Freezer-used safety valves
Freezer used safety valve is suitable for refrigeration equipment, used as equipment overpressure protection device, when the device operating pressure increases and exceeds the allowable value, the valve automatically opens, and discharges rated medium in accordance with equipment operating requirements, in order to prevent equipment pressure continuing to rise, play a role in protecting the entire system. LDA-22C150T, LDA-22C300T type safety valve series are matching overpressure protection device for the freezer condenser, evaporator, product test and performance are in line with the U.S. ANSI B16.34, ANSI/ASHRAE15-78 and national GB12241 ~ 12243 and other relevant standards.
