The minimum pressure valve is composed of valve body, valve core, adjusting nut, spring, sealing element and so on. The minimum pressure valve is mainly used to establish the internal pressure of the unit, promote the lubricating oil circulation, and meet the working pressure of the load reduction valve. In addition, the minimum pressure valve also acts as a one-way valve to prevent the compressed air in the storage tank from flowing back to the air compressor during unloading operation.
(1) the disassembly of the minimum pressure valve: the structure of the minimum pressure valve is very simple, unscrew the nut between the spool and the valve body can take out the components inside, the minimum pressure valve spool of the small unit is placed in the valve body, the valve cover can be taken out of the internal components.
(2) Cleaning the minimum pressure valve: cleaning the minimum pressure valve according to the method of cleaning the load reduction valve.
(3) assembly of the minimum pressure valve: assemble components according to the disassembly steps, because the structure of the minimum pressure valve is very simple, the assembly process is not described, but it should be noted that, if there is a U-ring inside, you should pay attention to the direction of the U-ring.
(4) The minimum pressure valve is put aside to be loaded into the air compressor after the whole cleaning process is completed.
