VALVE - AUX RELIEF (Anderson SY105392)

A worn auxiliary relief valve can disrupt system pressure regulation, leading to erratic operation or component strain. This aftermarket replacement part references the Anderson catalog and cross-references part number SY105392. The valve type controls maximum pressure in a secondary circuit, opening to divert flow when a preset threshold is exceeded. A common failure consequence is that a stuck-closed valve may cause pressure spikes, risking seal or hose damage. Conversely, a stuck-open valve can result in insufficient pressure for the intended function. Keeping the valve in sound condition helps maintain consistent system response during repetitive cycles. Verify the serial number or application, then call (562) 693-7748.
