Instrument Bleed Ring Assemblies and Accessories

The Aegis® IBR (Instrument Bleed Ring Assemblies) valves are specifically engineered for applications where environmentally safe draining of process fluid is critical prior to the removal of the level or pressure transmitters. Our patent pending dead-space free design is dimensioned to directly adapt to direct mounted and remote diaphragm seals transmitters thus eliminating the need for unnecessary connections and potential leak paths.
