The Bellows Seal Gate Valve is a high-performance valve designed to ensure sealing integrity and prevent medium leakage. It utilizes bellows seal technology to effectively block fluid leaks that could cause environmental pollution or safety hazards. This valve is suitable for use in steam, thermal oil systems, heat exchangers, and other high-temperature, high-pressure fluid control applications. Its compact structure and easy maintenance offer long-term reliable sealing performance.
Designed specifically for deep cold medium working conditions such as LNG, liquid nitrogen, and liquid oxygen, it adopts special stainless steel or low-temperature alloy valve bodies. Through deep cold treatment, it ensures reliable sealing even in an extreme environment of -196℃. The innovative lateral maintenance port structure allows for quick replacement of the sealing components without disassembling the valve, significantly improving maintenance efficiency. The optimized double eccentric butterfly plate, combined with multi-level metal hard seals, achieves zero leakage and long service life under ultra-low temperature conditions. At the same time, it is equipped with a longened valve stem heat insulation structure, effectively blocking the conduction of cold energy.
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.
