Clean in Place or Steam in
Place (CIP/SIP)
To prevent valve plug closing, insert the CIP/SIP pin (key 30,
Figure 4) completely so that spring ball in the end of pin is
secured into the vent hole on the side of the spring case. Be
sure to insert pin when regulator is in the open position.
!
WARNING
The CIP/SIP pin must be removed before
regulator is placed in operation. The pin will
inhibit the proper operation and function of
the regulator and result in overpressure of
the downstream system.
Maintenance
!
WARNING
Before disassembling the regulator, isolate
it from the pressure system and release all
pressure from the regulator as specified in
the Shutdown section. Relieve all spring
compression and isolate regulator from the
pressurized system prior to removing the
clamp (key 15).
Due to normal wear that may occur, parts must be
periodically inspected and replaced if necessary. The
frequency of inspection depends on the severity of
service conditions. A preventative maintenance schedule
should be implemented that checks regulator setpoint
and lockup and that evaluates regulator performance to
the system requirements. Regulator performance outside
the system requirements will require either adjustment,
part maintenance or regulator replacement to meet
system requirements.
This section includes instructions for disassembly and
replacement of parts. All key numbers refer to Figure 4 or 5.
1. If damage to the diaphragm or seating surface is suspected
or to inspect other internal parts, loosen the locknut (key 17)
or locking lever (key 22) and turn the adjusting screw
(key 18) counterclockwise to remove all spring compression.
2. Loosen the sanitary clamp (key 15) to remove the spring
case (key 14). Remove the upper spring seat (key 11) and
regulator spring (keys 12 and 13, when applicable).
Note
The regulator should be taken out of the line if
the internal wetted parts need to be inspected.
If the regulator is kept in the line the plug could
fall into the inlet piping.
3. Remove body from the line to inspect the internal
wetted parts.

Note
If the product is disassembled and includes
a metal diaphragm, both diaphragm gaskets
(key 6) should be replaced to ensure a good
seal at the diaphragm flange.
If removed from the guide ring (key 9), the
piston ring (key 5) should be replaced.
Take care not to damage the piston ring
during replacement.
