INSPECTION AFTER REMOVAL

• Place a thread so that it is caught in the valves of the water control valve. Immerse fully in a container filled with water. Heat while stirring.

  

• The valve opening temperature is the temperature at which the valve opens and the water control valve falls from the thread.

• Continue heating. Check the full-open lift amount.

  Note:

  The full-open lift amount standard temperature for the water control valve is the reference value.

• After checking the full-open lift amount, lower the water temperature and check valve closing temperature.
