6. OVER-PRESSURE INDICATOR
Pressure indicators are used to control pressure in main or secondary tubing. They can be applied directly on the
alternate outlet/indicator port that is standard on all nPr divider elements. There are three types of indicators that
give a different visual indication linked to the pressure set on the device. Below are shown the characteristics of
each pressure indicator and the part number.
The burst indicator must be replaced on each overpressure event. The lubricant will be discharged to atmosphere
.
7. TUBING, FITTINGS AND VALVES
Tubing, fittings and valves used in conjunction with the divider must be rated at the max pressure which the system
can operate at. Below a selection of components that you can be useful to assembly the divider blocks.

(The pin remains locked in position
until reset manually for ease of
troubleshooting).
The Pin retracts once the pressure
drops back under the indicator
limit.
In this type the membrane breaks
in case the pressure overcome the
set pressure.
