First, the electric cryogenic valve Product Overview Haichuan Shanghai Valve Co., Ltd. of ZRSGW-P (M) electric cryogenic valve is determined by 3810 Series (PSL series) electric actuators with low temperature control valve body composition, containing feed service function, to accept a unified 4-20mA or 1-5V · DC standard signal, converts the current signal into a corresponding linear displacement, automatically controlled electric cryogenic valve opening, to the pressure of the fluid inside the pipe, the flow, continuously adjustable temperature, level and other process parameters. Electric cryogenic valve to reduce transmission, long-necked thin-walled structures. Features: electric control valve having a low temperature sensitive, simple connection, flow, volume, the adjustment accuracy. Electric cryogenic valve internal diversification structure, choose spool type structure according to the actual conditions. Applicable scene: electric control valve is suitable for low temperature lower than 0 ~ -250 ℃ state work, the electric actuator and the valve body with a long neck to take over the composition, long-necked take over the role is to make the stem seal the close work at room temperature, and to reduce the external heat passed.
