SV08-29 Heidefoss Series High Pressure Thread Plug-in Valve

We need to do some maintenance and cleaning when using the hydraulic reversing valve, so as to ensure the normal use and longer service life of the valve. Let's take a look at how to clean the valve.

1. When the hydraulic reversing valve is cleaned, it should be removed first. Remove it before cleaning. When the grease on the reversing plunger and sliding arm is used, a corresponding liquid or lubricating oil should be selected, so that it can work better.

2. The cleaning process must be carried out slowly. Do not drain all the residual liquid in the multi-way valve.

3. When cleaning the multi-way reversing valve with high pressure, steam or hot water, non-corrosive liquid should also be selected.

4. During the maintenance of the hydraulic reversing valve, it is necessary to test the cleaning liquid suitable for each model and make a choice before use.

5, be sure to disconnect the grounding wire of the electromagnetic coil, so as to avoid electromagnetic interference, and then use detergent or other liquids for cleaning.

6. When cleaning the interior of the multi-way reversing valve, the multi-way reversing valve should be closed first, and the hydraulic oil should be drained, and then the filter element and other parts should be removed for cleaning.

Elimination method of pressure failure of pilot relief valve

1. Disassemble the damping hole of the main valve core, clean it effectively and reassemble it;

2. Add filters or replace new oil on the equipment;

3, repair the spring in the valve or better new spring;

The above content is the reason why the pilot relief valve pressure shared by Xiaobian can't go up. When we know the reason, we can effectively eliminate it, hoping to help everyone.

First, the reason why the pilot relief valve pressure can't go up

1. If the main spool is not cleaned before assembly, the oil will be too dirty or debris will be brought in during assembly, which will lead to the blockage of the damping hole of the main spool;

2. The assembly quality is poor, so the accuracy is not high when assembling, and the clearance of the parts themselves is not well adjusted, so the main valve core is stuck in the starting position;

3. The return spring of the valve is broken or bent, resulting in the main valve core not being reset;
