This gas shutoff differs from other contemporary design in that Watts engineers have embodied the time tested Watts auto-thermatic thermal actuator principle along with a snap-acting trip latch which closes the valve at a definite controlled temperature.
Models LFL210-5 M2, LFLL210-5 M2 and LFLLL210-5 M2 feature extended shanks for use with the new generation of water heaters containing extra thick insulation.
- Seating - Buna N disc to metal seating assures positive seal for shutting off the gas to burner in the event of high water temperature conditions
- Reset Button - After operating from high temperature, the gas shutoff must be manually reset (opened). Pressing the reset button in as far as it will go and then releasing, opens the valve and allows gas to again flow to the burner
- Trip Latch Assembly - Snap acting latch releases the valve to closed at a definite controlled temperature. Stainless steel spring seats valve when trip latch releases valve to closed position
- Thermostat - Operates trip latch in response to water temperature. Thermobulb, temperature sensitive portion, is at end of extension tube for accurate response to tank temperature
