Overview
The ZDSP electric low-temperature regulating valve is composed of an imported electric actuator and an ultra-low temperature regulating valve body. The actuator contains feeding and clothing functions, 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 ..
Product Details
ZDSP electric low-temperature regulating valveIt is composed of imported electric actuators and ultra-low temperature regulating valve bodies. The actuator contains feeding and clothing functions and accepts a unified standard signal of 4-20mA or 1-5V · DCcurrent signalConvert into corresponding linear displacement, automatically control the opening of the regulating valve to achieve pressure control of the fluid inside the pipelineFlow rate, temperature, liquid levelContinuous adjustment of process parameters. The electric low-temperature regulating valve is suitable for working below 0~-196 ℃. It consists of an electric actuator and a valve body with a long neck connecting pipe. The function of the long neck connecting pipe is to seal the valve stem to work close to room temperature and reduce the input of external heat energy. To reduce transmission, the long neck adopts a thin-walled structure.
