What should be paid attention to when installing and using the regulating valve?

In the field use of regulating valves, many of them are not caused by the quality of the regulating valve itself, but caused by improper installation and use of the regulating valve, such as the installation environment, improper installation position and direction, or unclean pipelines. Therefore, the following aspects should be paid attention to when installing and using the electric control valve: (1) The regulating valve is a field instrument, and the ambient temperature should be in the range of -25~60℃, and the relative humidity should be ≤95%. If it is installed in the open air or in a high-temperature place, waterproof and cooling measures should be taken. Keep away from the vibration source or increase anti-vibration measures where there is a seismic source. (2) The regulating valve should generally be installed vertically, and can be tilted under special circumstances. For example, when the tilt angle is large or the valve itself is too heavy, the valve should be protected by...
