PL5

The PL5 is used as a sample/cycle method in boilers. The orifice restricts flow near the boiler sensor to prevent steam flashing during a sample. The PL6 can also be used as a PL5.

PL6

The PL6 is used for a continuous sampling of a boiler. The lower orifice bleeds a small sample across the sensor. The upper orifice is used with the motorized ball valve and opens when the conductivity is above set point.
