MODEL 81-RPD

DIFFERENTIAL PRESSURE RELIEF PILOT (NORMALLY CLOSED)

PRODUCT OVERVIEW

81-RPD Differential Pressure Relief Pilot

The 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 81-RPD valve is used for remote sensing of a differential pressure for normally closed applications.
