Advantages and Cleaning Precautions of Hydraulic Directional Flow Valve

To talk about directional valves, they are quite commonly used in the market, especially in some mechanical equipment. Hydraulic directional valves are divided into 2-way, 3-way, 4-way, and 5-way valves based on the number of paths controlled by the directional valve. By using the absolute movement of the directional valve spool and the valve body, the hydraulic system can perform carriage, stoppage, or direction-changing movements, thus driving the hydraulic actuator and its driving mechanism. So, what are the advantages of hydraulic directional valves?

Advantages of hydraulic directional valve

Regarding the advantages of the hydraulic reversing valve, those who understand it should know that it is mainly accurate in action, high in automation, stable and reliable in operation, but it needs to be equipped with a drive and cooling system, and its structure is relatively complicated. Valve flap structure is simpler and is often used in production processes with smaller flow rates. Hydraulic directional valves are an important fluid reversing device in industries such as petroleum, chemical, mining, and metallurgy. The 6-way directional valve is installed in the pipeline of the thin oil lubrication system to transfer and stop lubricating oil by changing the relative position of the sealing components in the valve.

Precautions for cleaning hydraulic reversing valve

When we use the hydraulic reversing valve, we need to carry out some maintenance and cleaning work, so as to ensure the normal use of the valve and prolong its service life, so how should we clean the valve?

• When cleaning the hydraulic directional valve, it should be dismantled first and then cleaned. When greasing the directional plunger and slide arm, a liquid or oil that corresponds to them should be selected to perform better.

• In the cleaning process, it is essential to proceed slowly, and do not drain all the remaining fluid in the multi-way valve.
  

• When cleaning the multi-way directional valve with high pressure, steam, or hot water, non-corrosive fluids should be used.
  

• When performing maintenance on hydraulic directional valves, it is necessary to test the suitable cleaning fluids for each model and make a selection before use.
  

• It is essential to disconnect the grounding wire of the electromagnetic coil to avoid electromagnetic interference before using detergents or other cleaning fluids.
  

• When cleaning the interior of the multi-way directional valve, the valve should be closed first, and the hydraulic oil drained. After that, the filter element and other parts should be dismantled for cleaning.
