Electric Valve Actuators

The QuickTrip uses a set of three unique rotary solenoids called limited angle torquers (LAT). The

permanent magnet rotor is directly coupled to the trip valve.

The position of the valves is sensed by two limit switches present on each of the electrical modules.

These limit switches are located on both the closed and tripped positions of the valves, allowing the user

to easily determine the position of each valve.

Electronic Driver Modules (PCB)

The printed circuit boards (PCB) are mounted on of the top of each valve module. The PCB(s) performs

the following tasks:

• Trip demand input

• Dual redundant power inputs

• Valve position feedback discrete outputs

• Visual valve position indication

Discrete outputs are provided for position feedback indication of each valve module. Within each valve

module, there are also four LEDs that indicate the current condition of the module as well as power

supply health. These LEDs are viewable through the module covers’ transparent sight window.
