Indicator Light Kit Manual Override Kits
Flush flexible manual overrides are standard on single
solenoid models in Series 16 and Series 27. Double solenoid
models in Series 21 and 27 have flush metal-button overrides.
Both types are non-locking.
Each of the buttons in the override kits below is made of metal
and is spring-returned. The locking type button, however,
can be kept in the actuated position by turning the slot in the
top of the button with a screwdriver.
Order by the kit numbers shown below.
An indicator light extends through the solenoid or pilot
cover and is illuminated when the solenoid is energized.
Such lights are standard on double solenoid valves in
Series 21 and 27.
An indicator light is available in kit form for single solenoid
models in Series 16, Series 21 (type O only), and Series 27.
Order kit number
