Import Electric Low-Temperature Regulating Valve Product Overview
Germany VordWODEImport electric low-temperature regulating valve is made of 3810、PSL、2SBSeries of electric actuators and ultra-low temperature regulating valve bodies are composed. The actuator contains feeding function and accepts unified4-20mAOr1-5V·DCStandard signal, converting current signals into corresponding linear displacements, automatically controlling the opening of the regulating valve to achieve continuous adjustment of process parameters such as pressure, flow rate, temperature, and liquid level within the pipeline. Electric low-temperature regulating valves are suitable for temperatures below0～-250Operates at °C, comprising an electric actuator and a valve body with a long neck pipe. The purpose of the long neck pipe is to enable the valve stem to seal at near room temperature and reduce the transmission of external heat energy. To minimize transmission, the long neck is designed with a thin-walled structure.Section 2: Imported Low-Temperature Electric Regulating Valve Key Technical Parameters

Overview of Low Temperature Principle:
Low-temperature valves are mainly used for cutting off, connecting, and regulating the flow of media such as liquid oxygen and liquid nitrogen in pipeline systems under low-temperature conditions. Applicable media temperature range:-196 ℃~-29 °F, Filling seals are available in both double packing and single packing forms, suitable for different applications. Double packing effectively prevents cold loss, enhancing the sealing effect, ensuring the medium does not leak, and keeping the handwheel at room temperature for smooth operation.-101"Super-low temperature valves with temperatures of 0℃ or below require that the critical components be finely machined after rough processing but before final finishing."100%Immerse-196The liquid nitrogen tank at -196℃ is used for "cryogenic treatment."
