DZDLP electric low temperature regulating valve

First, ultra-low temperature electric regulating valve DZDLP electronic long rod low temperature electric regulating valve overview:
Electric low temperature regulating valve is composed of imported electric actuator and ultra-low temperature regulating valve body. The actuator contains the feeding function, accepts the unified 4-20mA or 1-5V·DC standard signal, converts the current signal into the corresponding linear displacement, automatically controls the opening of the regulating valve, and achieves the continuous adjustment of the process parameters such as pressure, flow, temperature and liquid level of the fluid in the pipeline. Electric low temperature control valve is suitable for below 0 ~ -196ºC state of work, by the electric actuator and with a long neck nozzle of the valve body, the role of the long neck nozzle is to make the valve stem seal out of close to normal temperature work, and reduce the external heat energy into. In order to reduce transmission, the long neck adopts a thin-walled structure.
Two, ultra-low temperature electric regulating valve DZDLP electronic long rod low temperature electric regulating valve features:
The production of electric low temperature regulating valve has developed a strict manufacturing process and the use of special equipment, strict quality control of the processing of parts, after special low temperature treatment, the roughed parts are placed in the cooling medium for several hours (2-6 hours) to release stress, ensure the low temperature performance of the material, ensure the finishing size, in order to prevent the valve in low temperature conditions, Due to temperature change caused by deformation caused by leakage, valve assembly and ordinary valves are also different, parts need to go through strict cleaning, remove any oil, to ensure performance.
