Differential Pressure Relief Pilot
The model 81-RPD is a remote sensing, high capacity, spring and
diaphragm operated, normally closed, differential pilot. The inner
valve is held closed by the spring. When the pressure under the
diaphragm overcomes the combined forces of the spring setting
and the pressure above the diaphragm, the pilot opens. The model
81-RPD is used for remote sensing of a differential pressure for
normally closed applications.
