The cryogenic butterfly body can be provided in two structural forms, namely flange connection and butt. welding connection (both with inspection ports). The body with inspection ports can replace the valve internals online, making maintenance work extremely simple, which is conducive to the rational use of resources and saving maintenance costs. The extended valve cover + drip tray design ensures that the temperature at the stuffing box is above zero degrees, so that the connection between the stuffing and the stem will not freeze and lock. Through the use of three-dimensional simulation optimization design, effective control of material changes under cryogenic conditions, selection of high-quality materials and effective processing technology to meet the stable performance of materials under cryogenic conditions. This series of valves has good sealing performance, high reliability, light weight, compact structure, and no need toworry about abnormal increase in valve cavity pressure. lt isan ideal valve for conveying cryogenic media and can bewidely used in cryogenic conditions in liquefied natural gas,aerospace and other fields.
The valve disc of the ultra-low temperature swing check valve adopts a cantilevered swing structure, combined with precisely machined valve seat sealing surfaces, to achieve rapid response and reliable sealing, effectively preventing the reverse flow of the medium. The overall design of the valve complies with international standards such as BS 6364 and ISO 28921, and is suitable for low-temperature conditions in air separation plants, liquefied natural gas storage and transportation, and the chemical industry.
The Forged Steel Compact Globe Valve is a high-performance fluid control device, precision-engineered from premium forged steel material. It combines throttling and shut-off functions in one unit. Designed specifically for high-pressure and high-temperature applications, it features compact construction, reliable sealing, and extended service life, making it ideal for demanding conditions in petroleum, chemical, power, and other industries.
