The KBB is a fast acting thermally operated valve with a spring loaded trip mechanism and sealed temperature sensing system consisting of a bellows, capillary tube and sensor phial. The valve will snap closed when the temperature at the sensor phial exceeds the set value. The valve will remain in the shut-off condition until the appropriate action has been taken to restore normal operating conditions and the reset button has been pressed.
The valve can also be shut-off manually by pulling the reset button.
