●The valve features two parallel gate plates and a wedging device, updating the traditional single gate plate design.
●Sealing elements are designed as separate components, which prevents deformation from thermal expansion and temperature differences, ensuring a reliable seal.
●The materials used for the sealing components are resistant to wear and corrosion, enhancing the valve's longevity.
●It is equipped with a bidirectional forced sealing capability, which simplifies operations and ensures a dependable seal.
●The fully enclosed design of the valve provides excellent protection, allowing for operation in all weather conditions.

The valve disc of the Cryogenic 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 Cryogenic Single-seat Control Valve is specially designed for low-temperature working conditions ranging from -196℃ to +80℃. It features an integral forged valve body structure and is equipped with a bellows seal assembly to ensure reliable sealing under extreme temperature conditions. The valve core is designed with a parabolic or equal percentage flow characteristic, forming a precise fit with the hardened alloy valve seat to achieve precise control of the medium flow. The product complies with IEC 60534-4 and GB/T 4213 standards, and is suitable for precise regulation of low-temperature media such as LNG, liquid oxygen, and liquid nitrogen. The pressure rating covers ANSI Class 150 to 900, and is widely used in key areas such as air separation equipment and low-temperature storage and transportation systems.
Self-operated Temperature Regulator is an energy-saving control device that does not require external driving energy. It relies on the temperature of the medium being regulated as the power source and the changes in the medium to automatically adjust according to the preset value. It integrates detection, control and execution functions into one valve and forms an independent instrument control system.
