Solenoid Emergency Shut-off Valve Kit -
The same situation could occur in the event of a UV bulb failure (rare, but possible).
The solenoid emergency shut-off valve kit is installed at the output of your Trojan UV system and will physically close a valve in the event of a bulb burn-out, or power failure,
thereby preventing any contaminant from passing through the system untreated.
This feature will also turn off the water supply if there is a UV intensity loss (for models equipped with a UV intensity monitor). This kit is highly recommend for all homes with a known bacterial, virus, or cyst contamination problem, and for all homes with an electrical supply that is prone to frequent outages.

Solenoid Valve Switch Types
DIRECT-ACTING 2-WAY VALVES
Two-way valves are shut-off valves with one inlet port and one outlet port In the de-energized
condition, the core spring, assisted by the fluid pressure, holds the valve seal on the valve seat to shut off the flow.
When energized, the core and seal are pulled into the solenoid coil and the valve opens.
The electro-magnetic force is greater than the combined spring force
and the static and dynamic pressure forces of the medium.
Internally piloted solenoid valves are fitted with either a 2- or 3-way pilot solenoid valve.
A diaphragm or a piston provides the seal for the main valve seat.
