The electronic electric cryogenic control valve consists of a 3810 series electric actuator and an extended-stem cryogenic valve body. The valve body features a *compact structure with excellent low-temperature resistance, suitable for cryogenic and deep-cryogenic applications with medium temperatures ranging from -40°C to -196°C. The extended neck design of the valve bonnet ensures the packing operates at ambient temperature while minimizing external heat transfer. To further reduce thermal transfer, the extended neck typically employs a thin-wall construction with excellent low-temperature resistance. This configuration is specifically designed for precise control of low-temperature gases and fluids (such as liquid oxygen and liquid argon), maintaining process parameters at specified values.
