Valve opening temperature: 80 ± 1.5°C
2. Check that the amount of valve lift is at the
standard value when the water is at the
full-opening temperature.

mostat is fully closed, and use this measurement
to compare the valve height when the thermostat
is fully open.

Full-opening temperature: 93°C
Amount of valve lift: 9.5 mm or more
