The 1/4-Turn Ball Valve Kit is designed as an emergency shut-off to isolate the nitrous in the bottle from the engine compartment in case of an emergency. The valve is typically installed in the driver's compartment within reach of the driver. If an accident or fire occurs, the driver or emergency personnel need only turn the handle a 1/4 of a turn to stop nitrous flow to the solenoids.
