How To Maintain Cast Steel Stop Valve?

Cast Steel Globe Valve After the installation is completed and put into operation, it is necessary to pay attention to the maintenance of the cast steel stop valve. Only by doing a good job of daily maintenance can we ensure that the cast steel stop valve can maintain normal and stable operation for a long time, and our production work will not be affected.

The following are some tips for the maintenance of cast steel stop valves:

1. For idle valves, they should be stored in a dry, ventilated and cool place, and both ends of the valve passage should be blocked to prevent dust and impurities from entering.

2. Check the valve regularly, apply anti-rust oil on the outer surface of the valve body, and clean the dirt on the valve body in time.

3. After the installation work, the valve needs to be regularly inspected to ensure its normal and stable operation. The parts that need to be inspected are:

a. Whether the sealing surface of the valve is worn, if there is wear, it should be repaired or replaced in time.

b. Whether the trapezoidal thread of the valve stem and the valve stem nut is seriously worn, and whether the packing is outdated and invalid. Once a problem is found, it should be replaced in time.

c. Regularly check the sealing of the valve and deal with leakage in time.

d. The valve as a whole should be intact, including the bolts on the flange and bracket, and ensure that the threads are not damaged or loose.

4. If the external environment where the valve is located is relatively harsh and easily affected by bad weather, a protective cover should be installed on the valve.

5. Keep the scale on the valve intact, accurate and clear.

6. Do not hit or knock the valve that is working in the pipeline, and do not support heavy objects.

Whether the cast steel stop valve can operate normally is related to whether the project can proceed smoothly, so the maintenance of the cast steel stop valve must be taken seriously.
