When handle !0 is turned clockwise to
compress pressure adjustment spring i,
the pressure from the IN side passes
through diaphragm !1 , opens pilot valve
!2 , and enters upper pilot chamber !3 .
This pressure and the force generated by
pressure adjustment spring i act as
resistance, resulting in equilibrium. Then,
this pressure passes through diaphragm
y of the main valve and stem !4 , and
pushes valve (main valve) u open, thus
guiding the pressure to the OUT side. At
the same time, the pressure passes
through feedback hole !5 , and enters
diaphragm chamber !6 , thus establishing
the OUT side pressure (outlet pressure).
