Inlet valve for S28/185
(from S/N 9508/011935)
The water inlets have brass bodies with larger
cross section of the outlet in order to achieve a
shorter filling time for the machine.
Construction
The valve housing is made of pressed brass. The
spring-loaded plunger is made of stainless steel
and located at its lower end.
Operation
The valve is automatically operated by means of
a rubber diaphragm and a pilot valve in exactly
the same way as the supply injector valve.
NOTE: To strip, clean, re-assemble and
troubleshoot the inlet valve, follow the
instructions outlined for the supply injector
valve.
