Pressure Relief Pilot (Normally Closed Pilot)
The model 81-RP is a remote sensing, high capacity, spring and
diaphragm operated, normally closed pilot. The inner valve is held
closed by the spring. When the sensed pressure increases above
the spring setting, the pilot opens. The model 81-RP is used as
the standard pressure relief/sustaining pilot on all 106 and 206
series valves.
