1： It should be clear to all that the electric control valve is a kind of field instrument, so when installing the electric control valve, the temperature of the installation environment must be guaranteed, and it needs to be within the appropriate range. Generally speaking, the temperature of the installation environment, especially the lowest temperature, shall not be lower than - 25 ° C, and the highest ambient temperature shall not exceed 60 ° C. The humidity of the installation environment shall not be less than or equal to 95%. If the installation environment of the electric control valve is in the open air or in a very high temperature environment, in order to ensure the normal operation of the control valve and have a very good working efficiency, it is necessary to carry out a very professional waterproof treatment or cooling treatment on the control valve, so as to effectively avoid the damage of the electric control valve. The installation environment of the valve is in the earthquake prone area, so it should be installed in a place far away from the earthquake source or protected against earthquakes.
