Multi-way valveThe common fault is the operation failure. The straightforward point is that the hydraulic cylinder of the vehicle and the movement organization does not correspond to the movement of the multi-way valve control handle. The other is that the movements are very small and the movements of the systems are very slow.


due toHydraulic multi-way valveThe internal components are very fine, and the valve core that controls the action of the compact waste truck is very fine, and its fineness is the same as the thickness of our common needle tip, so it is very simple to damage and block.


In the actual application process, as soon as the multi-way valve shows a problem, we usually replace the valve block. Friends who do not touch the multi-way valve often replace the entire multi-way valve. The cost is often thousands of dollars. In fact, the multi-way valve It is composed of multiple valve groups, and each valve group is not related to each other. If we find that one handle does not work anymore, we only need to replace its corresponding valve group.


Before replacement, we can disassemble the multi-way valve and clean it. Most of the problems of the multi-way valve are caused by the blockage of the multi-way valve. Due to impurities in the hydraulic oil in the multi-way valve, perhaps the owner of the vehicle has not replaced it for a long time. The hydraulic oil causes the impurities in the oil to walk to the multi-way valve and block the multi-way valve. At this time, the multi-way valve will not operate, or the action may be slow.Let us say one more thing here. Regarding the newly purchased waste compaction vehicles, the hydraulic oil must be replaced once the vehicle is used for 3 months or 2 months. Since the new vehicle is in the running-in phase, iron filings and various components will occur in the system. Such impurities can easily block the multi-way valve.

Regarding the cleaning of the multi-way valve, we can use professional cleaning agents. If the conditions are limited, we can use organic solvents such as gasoline and diesel to clean. The oil in the multi-way valve is easily dissolved. Using high-power and high-pressure gas to flush the multi-way valve with high-pressure gas will also flush out fine dirt.
