Stollar Sage Pump Overpressure Valve SES450, SES500, SES8 (BES500/31)

The pump overpressure valve is an essential component for Sage Bambino (SES450) and Sage Bambino Plus (SES500) coffee machines. The valve kit helps maintain the correct pressure level by diverting excess pressure to the drain, thereby protecting your coffee machine. If the beverage volume changes during coffee preparation, the pressure gauge does not display pressure, or too much water accumulates in the drip tray, it often indicates a malfunction of the pump overpressure valve.
