Download Product Documentation

The Consolidated® Series 3500 Electromatic Ball Valve (EBV) is designed to provide automatic or manual over-pressure protection for steam boiler systems. Set to operate at a lower pressure than the spring-loaded safety valves, the EBV substantially reduces safety valve maintenance and increases boiler efficiency.
