Overview of electric low temperature control valve: The electronic electric low-temperature control valve is composed of 3810 series electric actuator and extended-rod low-temperature valve body. The valve body adopts a precise structure and has good low-temperature resistance. It is suitable for low temperature and deep cold of medium temperature -40℃~ -196℃ occasion.

10Electric cryogenic control valve
The function of the long-necked upper bonnet of the electric low-temperature control valve is to make the packing work at room temperature and reduce the input of external heat energy. In order to reduce the transmission, the long neck generally adopts a thin-walled structure, which has good low-temperature resistance. For precise control of the process parameters of low-temperature gases and fluids (such as liquid oxygen, liquid argon, etc.), the process parameters are kept at a given value.
Features of electric low temperature control valve:
The production of electric low-temperature control valves has developed a strict manufacturing process and adopts special equipment to strictly control the quality of the processing of the parts. After special low-temperature treatment, the rough-machined parts are placed in the cooling medium for several hours (2-6 hours). ) To release stress, ensure the low temperature performance of the material, and ensure the finished size to prevent the valve from leaking due to deformation caused by temperature changes when the valve is in low temperature conditions. The assembly of the valve is different from that of the ordinary valve, and the parts need to undergo strict Clean and remove any oil stains to ensure performance.
Working principle of electric low temperature control valve:
The electric low-temperature regulating valve contains the function of feeding clothes, accepts a unified 4-20mA or 1-5V·DC standard signal, converts the current signal into a corresponding linear displacement, and automatically controls the opening of the regulating valve to achieve the effect of the fluid in the pipeline. Continuous adjustment of process parameters such as pressure, flow, temperature, and liquid level.
