The SAP surge anticipator panel provides the interface between a customer supplied, system pressure switch and the Singer surge anticipating control valve. Together they provide protection against destructive pressure surges. The SAP panel energizes the control valve pilot solenoid on an abnormally low pressure reading and/or power failure to pumps. The 12 VDC pilot solenoid is energized to open the main valve and relieve the surge pressure from the system. The RPS-L&H-ET (ET- Electronically Timed) valve is equipped with a hydraulic pilot to relieve on abnormally high pressures.
