Operation Logic
When
①
the adjustment bolt is turned clockwise,
④
the adjusting spring will take the force pressing
⑤
the diaphragm and
⑥
the stem will move downward and the supply pressure (IN) will go out to the
secondary output port (OUT). When the pressure on the secondary port reaches set pressure, this
pressure is transmitted to the bottom of
⑤
the diaphragm through the output pressure sensing hole,
and the set pressure is maintained by balancing the force with
④
the adjusting spring. If the pressure
on the secondary port is higher than the set pressure, the pressure delivered through the output
pressure sensing hole pushes up
⑤
the diaphragm and opens between the diaphragm and
⑥
the
stem. It is discharged to the atmosphere through
③
the spring case hole to maintain the set pressure.
