Hydraulic Operated Directional Valve

Installation and use of the Hydraulic operated directional valve:

1. Before installation, Hydraulic operated directional valve should refer to the instruction manual of the product to meet your requirements.

2. The pipeline should be rinsed before use, and a filter should be installed if the medium is not clean to prevent impurities from hindering the normal operation of the Hydraulic operated directional valve.

3. Hydraulic operated directional valve is generally one-way work, can not be reversed, the arrow on the valve is the direction of movement of the pipeline fluid, must be consistent.

4. Hydraulic operated directional valve installation is generally the valve body horizontal, the coil is vertically upward, some products can be installed arbitrarily, but it is best to be vertical when conditions permit, to increase the service life.

5. Hydraulic operated directional valve should be heated or set up when working again in the icing place.

6. After the coil lead wire (connector) is connected, it should be confirmed whether it is firm, and the contact of the connecting electrical components should not be shaken, and loosening will cause the Hydraulic operated directional valve not to work.

7. Hydraulic operated directional valve for continuous production work, it is best to use a bypass, easy to maintain, does not affect production.

8. Hydraulic operated directional valve after long-term suspension should be used only after the condensate is drained; When disassembling and washing, each part should be placed in order and then restored to its original state.

How to repair the hydraulic operated directional valve:

1. Disassemble. Although the parts of the hydraulic operated directional valve are mostly bolted to each other, the hydraulic valve design is oriented towards non-disassembly, and without special equipment or expertise, forced disassembly is likely to cause hydraulic valve damage. Therefore, before disassembly, it is necessary to master the structure of the hydraulic valve and the connection method between the parts, and record the position relationship between the parts when disassembling.

2. Check and clean. Check the dirt deposition of the valve body, valve core and other parts, and remove the concentrated dirt with cotton yarn, brush and non-metallic scraper without damaging the working surface.

3. Rough washing. Place the valve body, valve spool and other parts on the tray of the cleaning tank and heat and soak. Compressed air is passed into the bottom of the cleaning tank, and the residual dirt is cleaned through the stirring of bubbles, and ultrasonic cleaning can be used if conditions permit.

4. Fine washing. Cleaning is carried out with high-pressure positioning of the cleaning solution, and finally dried with hot air. Enterprises with conditions can use existing cleaning agents, and individual occasions can also use organic cleaning agents such as diesel and gasoline.

5. Assembly. Assemble according to the hydraulic valve assembly diagram or the part assembly relationship recorded during disassembly, and be careful not to touch the parts when assembling. The original sealing material is easily damaged during disassembly and should be replaced during assembly.
