Features:

1.   Parts of minimum pressure valve such as valve body, valve core and so on hold the anti-oxidation and corrosion resisting protection using stainless steel material.

2.   In the condition of no oil lubrication, minimum pressure valve can operate well and has a reliable sealing in dependence to self-lubricating sealing elements.

Strengthened spring is not easily deformed and fatigued making minimum pressure valve a reliable opening pressure.

Operation:

1.Valve opening:

The valve opens when the increasing pressure in the valve exceeds the adjusted opening pressure. Start opening pressure is already marked in the product label.

2.Valve closing:

The minimum pressure valve begins to close, when the pressure at either valve inlet or valve outlet decreases to less than the opening pressure plus 1 to 1.5 bar.

• If the compressor is loading, the oil separator will be higher than the opening pressure

• If the compressor is idling, the oil separator will be maintained at approx the opening pressure

• It is shut tight, if the pressure at the valve inlet is lower than the pressure at the valve outlet by more than 0.5 to 1 bar.

• The non-return valve will close automatically if there is no air demand or the compressor is stopped.
