1.Obtain a container filled with water and place the thermo valve in it with a stick (approximately 6 mm in diameter) inserted. Gradually warm up the water while stirring, and check that the thermo valve opening temperature is within the standard value. The stick rises when the thermo valve opens.
Standard value: 75 ± 1.5°C
2.Warm up the water to the full-open temperature of the thermo valve, and check that the valve lift amount is within the standard value.

    Standard value: Full-open temperature 95°C
    Valve lift amount when it is fully opened: 3 mm or higher
note Measure the height of the fully closed valve in advance, and then measure the valve height at fully open temperature to calculate the lift amount.
