• Place a thread (A) so that it is caught in the valves of water control

valve (1). Immerse fully in a container (B) filled with water. Heat
while stirring.

• The valve opening temperature is the temperature at which the

valve opens and falls from the thread.

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

NOTE:
The maximum valve lift amount standard temperature for water
control valve is the reference value.

• After checking the maximum valve lift amount, lower the water

temperature and check the valve closing temperature. 

• If out of the specification, replace water control valve.

INSTALLATION

Installation is in the reverse order of removal.

Water Control Valve 

CAUTION:

Replace the rubber ring with a new one.
