Product Description
Cryogenic safety valves are used in applications in which system overpressure in a cryogenic system is not only an extraordinary emergency but may very well occur several times. In this regard, it should be possible to collect and reuse the cryogenic, vaporising fluid - typically helium - for efficiency and cost reasons.
During normal, trouble-free operation of a system, the safety valves must be very tightly sealed in order to prevent fluid leakage to the largest possible extent. In case of an overpressure building up in the system, the valves must be activated exactly at a specific pressure value and dissipate large, cryogenic mass flows. In doing so, the valuable fluid is not released into the environment, but rather forwarded into a buffer container. In contrast to conventional safety valves, the cryogenic safety valves are therefore always activated at the specified pressure, regardless of the pressure that prevails behind the valve. When the pressure falls below a specific value again, the valves are tightly re-sealed. This is all done automatically, without external energy.

Company Introduction
Chengdu Singoly Cryogenic Technology Co., Ltd. was established in April 2008. It is a technology-based joint-stock company specialized in the design, manufacture, sales and technical advisory services of natural gas liquefaction equipment and cryogenic equipment pressure piping components. , Zhongyuan and Southwest Sales Company. The company's registered capital is 19 million yuan and the employees are more than 100.
The company has gathered a group of experienced low-temperature processes and equipment, low-temperature special valve research and development personnel, including 18 people with intermediate and higher professional titles, some have obtained two national patents, with a unique frictionless structure to achieve a switching life of 1 million More than two times of leakage-free double eccentric plate butterfly valve and four-link butterfly valve level R&D personnel, there have been twelve national patents, based on the absorption of U.S.-Japan technology and made significant innovations in low-temperature storage application valve research and development personnel; also There are professional management personnel who have produced and manufactured LNG low temperature according to AP standards and PED legal requirements. The company has new CNC lathes, welding equipment, first-class low-temperature testing and inspection equipment and advanced CAD design center.
The company's professionally designed and manufactured valve varieties are: butterfly, membrane regulating valve, ball valve, globe valve, throttle valve, check valve, pressure reducing valve, safety, instrument valve, breathing valve, three-way switching reading and so on. The nominal diameter is up to 1600mm, the maximum pressure is 42MPa, the use temperature is -269℃, the maximum is +850℃, and there are manual, pneumatic, electric and other transmission methods. Mainly used in air separation equipment, natural gas liquefaction separation equipment, petrochemical tail gas separation equipment, LO2, LN2, LAr, LH2, LCO2 low temperature storage and transportation equipment, pressure swing adsorption oxygen production, nitrogen and hydrogen recovery equipment, ethylene high temperature cracking device, power station And other fields.
