Singer Valve - Model RPS-L&H-ET -Surge Anticipator Panel (SAP)

SHARE

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.

The SAP panel is equipped with adjustable digital delay timers that permit coordination of valve operation with pump start-ups, shutdowns, power failures and down surges.

The SAP panel comes equipped with a long life, high capacity 12 VDC battery, industrial grade battery charger with over current and polarity protection, door mounted volt meter and battery test feature. The logical arrangement of indicator lights and the volt meter provide easy supervision of the sequencing and the operating status.

SAP Panel Surge Anticipating Panel

  • The surge anticipator panel shall be a Singer Valve model SAP, powered by selectable 120 VAC / 60 Hz source and complete with un-interruptible 12 VDC battery back-up and charger. Logic module, relays, battery and charger shall be housed inside a NEMA 4 rated rain tight enclosure. Logic module, relays, and fully labelled connection terminals shall be housed inside a NEMA 4 rated rain tight enclosure.
  • The surge anticipator panel shall open the electronic surge anticipator valve for a predetermined time after pump power failure or pressure down surge, in anticipation of a returning surge wave.
  • The surge anticipator panel shall accept a pressure switch dry contact and auxiliary pump motor starter dry contact for proper interface with the pumping system.
  • Three adjustable digital timers shall be provided: Start-up timer, surge anticipator timer, and shut-down timer.
  • The surge anticipator panel shall use a pre-programmed logic module to provide proper sequencing and digitally adjustable delay timer adjustments.
  • A system test button shall simulate surge condition and open the valve.
  • Prior to shipment, the panel shall undergo full function and operational tests.
