Type 650 Positive Bias Relay

The Type 650 positive bias relay is a signal operated regulator that provides an output pressure that is the sum of the input signal pressure plus a preset bias.

The unit allows flow capacities up to 50 SCFM with minimal pressure drop. An aspirator tube at the output maintains the set pressure under varying flow conditions by causing the main supply valve to open and close proportionally to the flow demand.

There is a choice of four adjustment ranges for the positive bias settings. This unit is most often used for conversion of a low flow control signal to the higher flow requirements of an operating system.
