    Details Introduction

    Operation:

    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.

    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 stopp
