VII. INTRODUCTION: ELECTRIC VALVES
1. Electric Controller Overview (UBEC1, UBEC2, UBEC3, UICS2)
Designed with precision in mind, the electric valve controller and integrated electronic display is easy to
operate. Monitor the valve position on a 10 LED valve position indicator. All controls and indicators are
located on the front of the control and display module. Controls are simple push buttons.
UBEC1 – Valve control with valve position indicator.
UBEC2 – Valve control with valve position indicator and digital pressure display.
UBEC3 – Valve control with valve position indicator, digital pressure display, and digital flowmeter.
UICS2 – Valve control with valve position indicator, digital pressure display, and CAF control with on/off
input as well as selectable preset positions for wet, medium, and dry CAF.
Electric Actuator Overview (E3F, E4F)
The E3F and E4F Unibody electric actuators have been designed to further simplify the use of electric valves
on a fire fighting apparatus. The control logic has been relocated to the top of the valve. This increases the sim-
plicity of wiring the valve as well as broadening the options for controlling the valve. The E3F and E4F
electric actuator utilize the J1939 data bus for control communication. All electronic components have been
potted with a two part epoxy to ensure a water tight seal.
