Technical performance of Goetze Cryogenic Relief Valve

The Goetze cryogenic safety valve components are precision-machined after cryogenic treatment to ensure durability and reliability. The valve features a fully enclosed bonnet and cap structure, which guarantees that during discharge, the medium is safely vented through the outlet pipe without external leakage, effectively preventing dust and other impurities from entering.
The maximum pressure can reach 4.0MPA
Some models can be dispatched after adjusting and setting the pressure parameters according to customer requirements.
This product series is widely used in the fields of petroleum, chemical engineering, boilers, power stations, metallurgy, nuclear power, and scientific research. It is primarily responsible for safety pressure control in liquefied natural gas (LNG) systems and cryogenic liquid storage and transportation equipment. It also provides overpressure protection in processes such as air separation and industrial gas production.
