High Pressure Manifold

Replace the High Pressure Manifold if it is visibly cracked, broken and leaking. Replace the High Pressure fitting
O-Rings if damaged, worn, or leaking.

High Pressure Transducer

Pressure Transducers are irreparable and cannot be calibrated. If inoperative, check connections at the transducer
and at the Printed Circuit Board to ensure that there is no visible corrosion or loose connections.

Automatic Motor Actuated Back Pressure Regulator

The Motor Actuator and Gear Assembly are irreparable. If the motor has been confirmed to be non-operational,
then it must be replaced.
Caution: If the valve stem and or Motor gear shaft is rotated separately from the other they must be replaced.
If the coupler set screws have become loose allowing the shafts to rotate independently, or if repair has been
performed where in the valve has been separated from the coupler or the motor gear shaft, then the motor
gear shaft and the valve stem MUST BE REPLACED. If the valve stem has rotated separately from the motor
gear shaft the control logic will not be able to maintain and control the system operating pressure.
Caution: Do not bench test the Electric Motor Actuator! DO NOT APPLY DIRECT VOLTAGE TO THE
ACTUATOR. Bench testing of the motor can cause physical damage to the positioning signal device located
within the Actuator assembly.
Important: Be sure to perform a function test on the Electric Motor Actuator as described in the topic
System Check
Valve Packing Leak
If the Back Pressure Regulator valve leaks from the valve stem, lightly tighten the packing gland nut located below
the valve stem. Should adjustment fail to stop the leak, replace the entire valve.
