Spray Valves

The Sterling tray assembly, as well as the spray valve, is designed to be resilient: able to withstand upset and extreme conditions resulting in reduced downtime. Rugged construction combined with lower steam pressure drop extends deaerator life even under the most severe operating conditions.Allied's deaerators utilize the unparalleled Sterling spray valve for maximum dissolved gas removal. The spray valve is cast from rugged, non-corrosive type 316L stainless steel to ensure maximum life. This self adjusting, non-guided spray valve can handle flow up to twice its rated capacity, while maintaining an effective, consistent spray pattern. Because the Spray Valve is hydraulically balanced and non-guided, solid particles and debris pass harmlessly through the valve without clogging or reducing performance. As described in the deaerating principle, the thin film of feedwater sprayed into the steam atmosphere provides rapid heat ransfer and gas removal. The spray valve produces that essential thin cone of feedwater consistently over its operating range, resulting in continuous deaerating performance.
