CROSS SECTION
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(11), spring(8, 9) for setting secondary
pressure, return spring(4), stopper(7), spring seat(5, 6) and spring seat(10). The spring for setting the
secondary pressure has been generally so preset that the secondary pressure is 5 to
20.5kgf/cm
2
(Depending on the type). The spool is pushed against the push rod(12, 13) 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.
