The 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. Model 81-RP pilot is used as the standard pressure relief/sustaining pilot on all 106 and 206 series valves.
