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.

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).
