Desuperheaters for Food Processing Steam

B-Tech Valve offers fixed-nozzle spray-ring designs and a probe-type variable-nozzle design. The SPAD and Steam Attemperator use a spray ring and clamp between steam pipe flanges, while the LPD uses a fully actuated variable-nozzle control valve with a 90-degree flanged insertion. Selection is based on line size and application requirements.

The spray-ring desuperheater designs are fed water from a separate temperature control valve. This arrangement allows the water supply and steam-conditioning function to be coordinated with the process control system. Final water-control requirements, injection conditions, and sizing should be reviewed against the steam system operating data.

The listed products are available in ASME B16.34 pressure classes 150, 300, 600, 900, 1500, 2500, and 2700. The suitable class depends on the steam piping design conditions and the required pressure rating. B-Tech Valve can use the application information to identify an appropriate product configuration.

The listed SPAD, Steam Attemperator, and LPD products are temperature rated up to 1,200°F (650°C). Actual operating suitability must be confirmed against the complete steam-system conditions, including temperature, pressure, flow, water supply, and downstream equipment requirements.

A spray-ring design may suit applications using a fixed-nozzle arrangement and flange-clamp mounting. The LPD probe-type design uses a variable nozzle and fully actuated control valve for steam pipes 6 inches and larger. Selection should consider pipe size, control requirements, installation space, pressure class, temperature, and process conditions.

Yes. B-Tech Valve provides application-engineered, application-sized desuperheater and attemperator products. Useful selection information includes steam pressure, temperature, flow, pipe size, desired outlet conditions, available water supply, pressure class, and installation details. This information supports evaluation of the SPAD, Steam Attemperator, or LPD configuration for the process system.
