Fisher Control Valve
Fisher DMA/AF-HTC Desuperheater
Fisher DMA/AF-HTC is functionally equivalent to the Fisher DMA/AF, however it is structurally suited for more severe applications. The most common applications include boiler interstage attemperation, where the desuperheater is exposed to high thermal cycling and stress, high steam velocities and flow induced vibration.
- Nozzles can be easily removed, maintained, or replaced without having to replace the entire unit.
- Fisher DMA/AF-HTC uses a forged construction, optimized to move weld joints away from high stress regions.
