1. First check whether the solenoid valve is normal, whether the coil is burned out, and whether the solenoid valve core is blocked by stolen slag. If this is the case, your solution is to replace the solenoid valve, replace the coil with pneumatic control valve, and remove the stolen slag.
2. What to do if the pipeline is distorted or flattened.
Professional manufacturers tell you the solution, the good way is to correct or replace the pipeline, so as to solve the substantive problem.
3. If the present handle is in the manual orientation, the user must pull the handle to the pneumatic automatic orientation.
4. If there are impurities in the valve to the ball core stuck does not run, it is necessary to eradicate impurities, and replace the valve or components that have been damaged, electric control valve.
When it is cold in winter, the ambient temperature is relatively low, so it is very simple to form the pipeline freezing, so the user must add water removal equipment.
With the development of China's industry, pneumatic control valve in metallurgy, petroleum, chemical and other fields of application more and more widely, pneumatic control valve operating conditions will directly affect the process of automatic control, so in addition to the correct use of methods to ensure the quality of valve products, improve after-sales service is also the demand for valve manufacturers to pay attention to the use of pneumatic control valve, should pay attention to the following matters:
1. In order to ensure the normal operation of the pneumatic control valve, the new valve should first check whether the nameplate on the valve meets the planning requirements before use.
2. Experiments on pneumatic control valves: basic error limit, total stroke deviation, return difference, dead zone, and leakage (check for strictly required working conditions).
3. If the pneumatic control valve of the original system is repaired, in addition to the verification above the requirements, the old valve packing and sealing joint number should also be checked.
