Fairchild M91 Higher Pressure Selector Relay

FeaturesSmall, rugged design.Soft seat construction.Low selection differential.Fast response.Automatic switching.BenefitsSuitable for installation where space is limited.Assures positive shutoff.Allow precise control of switching function.Well suited for control in critical loops.Eliminates manual monitoring of signal pressure.

The Model 91 High Pressure Selector Relay is designed to select the higher of two signal pressures, and to provide a continuous output pressure (or pressure range) to a controller. The ability to precisely control pressure switching and pressure monitoring functions make the Model 91 the logical choice in dead end or low flow applications such as precision control loops.
