Air filter regulator, YT-200 / 205 / 220 / 225, receives the main supply air pressure and
supplies to the desirable level of pressure to a positioner or other pneumatically operating
devices.
2.2 Main Features and Functions
➢Maintains desirable pressure level, regardless of fluctuation of the main supply pressure.
➢5 micron filter filters most particles in the main supply pressure.
➢Relief function is available which discharges to the atmosphere, if the output pressure is
higher than setting pressure.
➢By using aluminum or stainless steel body, it has high durability in various environments.
➢Manual or Auto draining is available.

2.6 Operation Logic
When ① the adjustment bolt is turned clockwise, ④the adjusting spring will take the force pressing
⑤the diaphragm and ⑥the 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 ⑤the diaphragm through the output pressure sensing hole,
and the set pressure is maintained by balancing the force with ④the 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 ⑤the diaphragm and opens between the diaphragm and ⑥the
stem. It is discharged to the atmosphere through ③the spring case hole to maintain the set pressure.
