Description
The Morrison Bros FIG 474 is an angle-type emergency shutoff valve designed for installation in the bottom outlet of small farm storage tanks. A spring-loaded disc is held open by a UL-listed 165°F fusible link during normal operation. In the event of fire, the fusible link activates, releasing the spring to close the valve and stop product flow. The male-threaded inlet installs directly into the tank with a female-threaded outlet for downstream connection.
