Teddington KBB Remote Acting Fire Valve


The KBB is designed as a fire safety shut-off valve for use on oil burning equipment. The valve is to be installed in the oil supply pipeline outside the building with the sensor mounted firmly inside the appliance above the burner. The capillary should then be run in a protected position without over-sharp bends particularly near the sensor and valve. 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.
