Replacing Obsolete or Discontinued Desuperheaters

Selection should consider the steam pipe size, pressure and temperature conditions, connection arrangement, required water control, and the function of the existing unit. B-Tech Valve products include flange-clamp mounting, 90° flanged insertion, and component-level replacement options. Existing drawings, nameplate information, and operating details can support application sizing.

The SPAD Small Pipe Attemperator Desuperheater uses a fixed-nozzle spray ring that clamps between two steam pipe flanges. The LPD Large Pipe Desuperheater uses a probe-type variable-nozzle, fully actuated control valve and desuperheater assembly for steam pipes 6 inches and larger. Both designs are application-focused steam-conditioning solutions.

Yes. Replacement Parts for Desuperheater Valves are available as component-level replacement solutions. They are intended for applications requiring replacement components rather than a complete new assembly. Compatibility should be reviewed against the existing valve design, pressure class, temperature requirements, and operating conditions before ordering.

The product range includes ASME B16.34 pressure classes 150, 300, 600, 900, 1500, 2500, and 2700, depending on the product and configuration. Products are rated for temperatures up to 1200°F (650°C), subject to the selected design and application. Confirm the required rating during technical review.

These products are used in power plant and process plant steam systems for steam attemperation and conditioning. Applications include protecting piping and steam traps, protecting rotating seals, increasing steam heat-transfer capability and flow, decreasing boiler loads, and reducing fuel costs where the application supports those objectives.

Useful information includes the existing product identification, pipe size, flange or insertion arrangement, pressure class, operating temperature, steam conditions, water supply details, and available installation drawings. Information about the intended protection or control objective also helps determine whether a complete desuperheater, an alternative design, or replacement components are most appropriate.
