Rate of Flow Control Pilot
The model 160-RF is a spring and diaphragm operated, normally open pilot designed to sense a differential across an external orifice plate. The inner valve is held open by the spring. A sensing port is provided in the spring casing, above the diaphragm. When the control pressure below the diaphragm exceeds the combined forces of the spring and the sensing pressure, the pilot valve closes. The model 160-RF is used as the standard rate of flow control pilot, in conjunction with an external orifice plate, on all series 106 and 206 valves.
