High Temperature Dampers are used for modulation of vapor flows in various types of applications. Typically, these applications are high temperature, located in waste heat recovery systems, boiler system, and heater systems. These modulating dampers use a butterfly valve configuration, and can be manufactured in various materials to enable use in these difficult services. In addition, they can be water cooled or refractory lined to protect the metal from extreme temperatures. For shutoff applications, we supply slide gate valves, which can also be manufactured to withstand the same extreme temperatures.
