Capillary thermostat WKF series is designed for gas valve which used in gas water heater thermostat, gas stoves and other gas applications. It has very precision bellow movement based on the principle of liquid expansion and contraction, which will control the flame of gas valve through sensing the air temperature by capillary thermostat.
