General Description
Spring Housing (1):
– The Pilot Spring Housing is
provided with a 1/4 inch NPT vent connection which
may be piped to a safe area or pressure loaded for
remote control of the pressure setting. The Main Spring
may be changed by simply removing the Closing Cap
(1A).
Body lnsert Assembly (2):
A removable Body lnsert
Assembly (cartridge), at the bottom of the Pilot Body,
contains the inner valve mechanism. The cartridge may
be replaced with a spare unit for fast troubleshooting
or repair. The Body lnsert Assembly is also field
repairable. The same Body lnsert Assembly is used
on the Pre-Pilot section of the Series 22 Pilot and the
cartridges are interchangeable.
lnlet and Loading Ports (3):
The INLET port is where
upstream supply pressure is connected to the Series 22
Pilot Assembly. The LOADING port is used to connect
the controlling signal from the pilot to the loading port
on the actuator.
Sensing Port (4):
The Series 22 Pilot has multiple
Sensing options with the standard configuration being
the ½” NPT connection directly connected to the
FlowMax НР actuator with flow passing through the
Type 27 Restrictor, to the Upper Actuator Housing, then
downstream to the point of control.
lntegrated Check Valve (5):
Prevents damage to the diaphragm in situations
where pressure is reversed and downstream pressure
exceeds upstream pressure.
Diaphragm Spacer Assembly (not shown):
The
addition of this assembly converts the Series 22 Pilot
into the high pressure Series 22Н. It reduces the pilot
diaphragm area and increases the spring range of the
black and white/green springs.
