Positive Bias Relay By Controlair Inc.

We are manufacturing, exporting and supplying huge range of Positive Bias Relays in Pune, Maharashtra, India. The Type-650 positive bias relay is a signal operated regulator that offers an output pressure that is the sum of the input signal pressure plus a preset bias. The unit provides flow capaci ties 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 supp!y 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. Apart from this, these can be availed from us at reasonable cost.
