Variable Orifice Desuperheaters and Valves

The LPD Large Pipe Desuperheater is intended for steam pipes 6 inches and larger. B-Tech Valve also identifies SPAD spray-ring desuperheaters for steam pipes 4 inches and smaller. Product selection should be based on line size, steam conditions, required control, and the application details provided for engineering review.

The products are offered for ASME B16.34 pressure classes ranging from 150 through 2700. The LPD product information specifically lists classes 150, 300, 600, 900, 1500, 2500, and 2700. The appropriate class should be selected against the steam system design requirements and applicable project specifications.

B-Tech Valve products are temperature rated up to 1,200°F (650°C), with the LPD Large Pipe Desuperheater listing the same maximum rating. Actual suitability depends on the complete steam application, operating conditions, materials, pressure class, and installation requirements. Application details should be reviewed before selecting a configuration.

The LPD Large Pipe Desuperheater is a probe-type variable nozzle control valve and desuperheater for steam pipes 6 inches and larger. It uses a flanged insertion at 90° on the steam pipe and combines variable-nozzle control with desuperheating to support steam flow, heat transfer, and protection of downstream steam-system components.

B-Tech Valve supplies replacement parts for desuperheater valves, including American-made components and parts compatible with ASME B16.34 pressure classes 150 through 2700. Parts are stocked in-house for quick turnaround availability. Buyers should provide the existing valve information, service conditions, and required component details to support compatibility review.

Applications include power plants, process plants, industrial boiler and cogeneration steam plants, refineries, and other high-temperature steam systems. The equipment can support steam attemperation, heat-transfer improvement, piping and steam-trap protection, rotating-seal protection, steam-flow optimisation, and reduced boiler loads when correctly selected for the system.
