During operation, minimum pressure valve (Vp) keeps the pressure in the separator tank (OT) above a
minimum value, required for lubrication. An integrated check valve prevents the compressed air
downstream the valve from being vented to atmosphere during unloaded operation.

When the compressor is stopped, inlet valve (IV) closes, preventing compressed air and oil to flow to the
air filter.

Regulation

Unloading valve (loaded condition)

• When the net pressure is below the loading pressure, solenoid valve (Y1) is energised.

• The space above unloading valve/blow-off valve (UV) is connected with the oil separator tank

pressure (1) via the solenoid valve.

• Unloading valve/blow-off valve (UV) moves downwards, closing off the connection to channels

(2) and (3).

• Underpressure from the compressor element causes loading plunger (LP) to move downwards

and inlet valve (IV) to open fully.

Result: air delivery is 100%, the compressor runs loaded.

• If the air consumption is less than the air output of the compressor, the net pressure increases. When

the net pressure reaches the unloading pressure, solenoid valve (Y1) is de-energized.

• The pressure above unloading valve/blow-off valve (UV) is released to atmosphere and the

space above valve (UV) is no longer in connection with the oil separator tank pressure (1).

• Unloading valve/blow-off valve (UV) moves upwards, connecting the oil separator tank

pressure (1) with channels (2) and (3).

• The pressure in channel (2) causes the loading plunger (LP) to move upwards, causing inlet

valve (IV) to close, while the pressure is gradually released to atmosphere.

• The pressure in the separator tank stabilizes at low value. A small amount of air is kept drawn in

to guarantee a minimal pressure, required for lubrication during unloaded operation.

Result: air output is stopped, the compressor runs unloaded.
