The construction of the pilot valve is shown in the attached cross section drawing. The casing has
vertical holes in which reducing valves are assembled.
The pressure reducing section is composed of the spool (3), spring (5) for setting secondary pres-
sure, return spring (7), spring seat (6) and shim (4). The spring for setting the secondary pressure
has been generally so preset that the secondary pressure is 5 to 20.5 kgf/cm
2
(depending on the
type). The spool is pushed against the push rod (9) by the return spring.
When the push rod is pushed down by tilting the handle, the spring seat comes down simultaneously
and changes setting of the secondary pressure spring.
