Adjusting the Pressure Relief Valve
When placing the operator into service, pressure relief valve
adjustments are required! To provide instruction during
installation, a cautionary yellow tag is wire tied to every pump
pack. The same instructions are provided in this section.
Pressure relief valves differ depending on the model.
Tools Needed: 5/3 2 " hex key, ½" and 9/1 6 " box end wrenches.
NOTICE: Pressure relief valve adjustments establish the threshold for the inherent entrapment sensor (IES). The
optimal pressure setting produces uniform gate travel and trips the IES when the gate encounters an obstruction.
