Spray Valves
Ecodyne spray valves are constructed of 316 series stainless steel, and are attached by three (3) bolt assemblies.
The body and single piece stem and plug are investment cast for precision and reliability. The valves are spring loaded and self-adjusting to assure that the water is sprayed in controlled thin films at loads form less than 10% to over 150% of rated capacity. This feature assures heating of inlet water to within 2º F of the steam temperature at all load conditions and, in addition, provides proper distribution to the second stage deaerator.
The controlled spray pattern ensures maximum efficiency of the internal vent condenser. The valves are installed in the heater so that they are easily accessible for inspection. Experience has show that this spray valve construction is free from difficulties of scaling or corrosion. The spray valves are designed to give minimal pressure drop.
