(1) The dispatching valve belongs to the on-site dashboard, and the standard working temperature should be in the field of -25-60 °C, and the air humidity should be ≤ 95%. If it is installed outdoors or in a high-temperature place, moisture-proof and temperature-reducing measures should be used. In areas where there is an epicenter, it is necessary to eradicate the source of vibration or improve vibration isolation measures.
(2) The dispatching valve should generally be installed vertically, and it can be tilted under unique circumstances, such as the tilting angle is quite large or the dispatching valve itself is very large, and the valve should be protected by supporting plates.
(3) The pipeline for installing the electric dispatching valve generally does not need to be too high from the road surface or wooden floor, and the service platform should be set as far as possible when the height and width ratio of the pipeline exceeds 2m, so as to facilitate the operator's wheel and facilitate the opening and maintenance.
(4) Dispatch the valve to be installed before the treatment pipeline is opened and cleaned up, and the waste and weld through are removed. After installation, in order to ensure that the residue is not left in the valve body, the gate valve should be opened again, that is, all the gate valves should be opened when entering the substance to prevent the residue from stuck. After using the handle arrangement, it should be restored to the original neutral position.
(5) In order to make the self-operated dispatching valve open again in the case of common faults or maintenance, the dispatching valve needs to add a bypass valve pipeline. In addition, it should be noted that the installation part of the electric dispatching valve is not in line with the rules of the whole process of processing technology.
(6) Part of the installation of the electrical equipment of the self-operated dispatching valve shall be opened according to the construction rules of the relevant electrical equipment project. If it is an explosion-proof product, it should be opened and installed in accordance with the rules of the "Standards for Electrical Equipment and Installations in Explosive Hazardous Places". For example, the on-site transmission line is selected to install SBH type or other six-core or eight-core rubber sleeve with a diameter of 11.3mm. In the use of maintenance, it is forbidden to connect the power supply to open the meter cover for maintenance and open the explosion-proof surface for pry in flammable and explosive places. Others do not need to bump or scratch the explosion-proof surface during disassembly, and should be transformed into the original flameproof rules after repair.
(7) After the reducer of the electric actuator is disassembled, it should be carefully lubricated and lubricated, and the low-speed motor generally does not need to be disassembled for oiling. After the assembly line, it should also be checked whether the valve position is consistent with the valve position opening indication.

The self-operated control valve is different from that without a commander
The self-operated conditioning valve, also known as the self-operated control valve, relies on the pressure and temperature of the medium flowing through the valve as the energy source, and uses the reaction signal (pressure, pressure difference, temperature) at the output end of the valve to be transmitted to the actuator through the signal tube, and drives the valve disc to change the opening of the valve and reach the conditioning pressure.
