Thermo Valve Check

THERMO VALVE CHECK





1. Obtain a container filled with water and place the thermo valve in it with a stick [approximately 6 mm (0.24 inch) 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 (167 ± 2.7° F)

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: 3 mm (0.12 inch) or higher [amount of thermo valve lift when it is fully opened]

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.
