The RPP0143 conversion kit upgrades the pressure sensing line on a Tornatech fire pump controller from a 2-way to a 3-way solenoid valve arrangement. The kit is built around the SOLGRA0007 (ASCO028) 24 Vdc solenoid valve, rated from 0 to 500 psi and supplied with 15-inch leads.

The 3-way arrangement supports the controller's weekly automatic test: on command, the solenoid relieves the sensing line to simulate a system pressure drop, the controller starts the pump, and the valve then reseats to restore normal pressure sensing — no manual valve operation required. If your controller was supplied with the older 2-way setup, this kit brings it up to the 3-way configuration.

Fits Tornatech model GPD, GPX, and GPX+GPU fire pump controllers. Not sure whether your installation needs the conversion? Veteran-owned Cybertronic Controls in Hammond, Louisiana can walk you through it — call 985-351-5681 before you order.
