02250177-150 Alternative Screw Air Compressor Spare Parts For Sullair

Product Description:

The minimum pressure valve is composed of a valve body, valve core, spring, sealing ring, adjusting screw and so on. It is installed at the outlet of the oil separator. Its role is to keep the pressure in the oil separation tank from falling below 0.4Mpa, so that the compressed air containing oil can be better separated in the separator and the loss of lubricating oil can be reduced.At the same time, it can ensure the gas pressure needed to establish oil pressure.The minimum pressure valve also functions as a check valve to prevent the reverse flow of compressed air in the system during shutdown.The minimum pressure valve also functions as a check valve to prevent the reverse flow of compressed air in the system during shutdown.

The function of the minimum pressure valve:

1.The function of the minimum pressure valve is to buffer. When the machine is loaded, we assume that it is discharged into the atmosphere. The large pressure difference between the inside of the machine before and after the separation will all be added to the separator, causing damage to the separator core. hurt;

2.The oil lubrication of the machine is carried out by the pressure difference of the machine itself, without additional oil pump assistance, when the machine is in no-load state, a certain pressure is still required to maintain the oil circulation, so the intake valve is relatively closed, and the minimum pressure valve prevents pressure leakage , So as to ensure lubricating oil circulation.

3.The minimum pressure valve is mainly used to establish the internal pressure of the unit, promote the circulation of lubricating oil, and meet the working pressure of the relief valve.

4.In addition, the minimum pressure valve also functions as a one-way valve to prevent the compressed air in the air storage tank from flowing back to the air compressor when the unit is unloaded.
