electric regulating valveandpneumatic control valveIt is a precision instrument. No matter how good it is, if it is not installed according to the prescribed requirements, it cannot be used correctly, especially for new pipelines and valves. There will be many problems during transportation and installation. The correct installation method can ensure the normal operation of the regulating valve, which is also crucial for later maintenance, upkeep, and use.

1. During the initial operation and overhaul of newly installed regulating valves, it is important to take isolation or removal measures when blowing process pipelines to prevent blockages caused by welding slag, rust, etc. in the throttling and guiding parts of the pipeline, which can impede the flow of the medium. Alternatively, during the maintenance of the regulating valve, if the packing is too tight, it can increase friction and cause small signals to fail and large signals to overreact.

2. When installing a pneumatic control valve, attention should be paid to the air opening and closing of the control valve to prevent valve leakage caused by the improper length of the control valve stem.

3. To prevent cavitation, the following points should be noted during the initial selection and installation: 1) Try to install the regulating valve at the lowest position of the system, which can relatively increase the inlet and outlet pressure of the regulating valve; 2) Install a shut-off valve or orifice plate upstream or downstream of the regulating valve to change the original pressure drop characteristics of the regulating valve; 3) Specialized anti cavitation components can also effectively prevent flash evaporation or cavitation, as they can alter the flow rate of the fluid within the regulating valve, thereby increasing internal pressure; 4) Try to choose a regulating valve with a harder material, because in the event of cavitation, such a regulating valve has a certain degree of erosion resistance and wear resistance, which can allow cavitation to exist under certain conditions without damaging the internal components of the regulating valve. On the contrary, for regulating valves made of soft materials, when cavitation occurs, the internal components of the regulating valve will quickly wear out.

4control valveGenerally, it should be installed upright, and if it needs to be tilted, it should be supported.

5. The flow direction of the medium must be consistent with the arrow on the valve body.

6. The installation position of the regulating valve should be easy to observe, operate, and maintain.

7. The signal tube of the actuator should have sufficient flexibility and should not hinder the action of the actuator.
