2-4-1 The hydrostatic test pressure shall be, as a minimum, 1.5 times the maximum allowable working pressure with a tolerance of non-negative and plus 5%. Painting shall not be performed until the hydrostatic and the air leak test have completed.

The working principle of the minimum pressure valve of the air compressor: When the pressure of the air compressor system is lower than the set minimum working pressure, the minimum pressure valve opens, allowing air to flow through the valve into the system and increase the pressure of the system;.

We need a minimum pressure to circulate the oil. Circulation of oil is critical for cooling of the rotary screws and for the lubrication of the bearings. A rotary screw compressor has no oil pump. The oil is pumped through the system by the differences in pressure that exists inside the compressor.
