Class 150 to 900 Desuperheaters for Process Steam

The products are offered in ASME B16.34 pressure classes 150, 300, 600, 900, 1500, 2500, and 2700. The category topic focuses on Class 150 to 900 applications, while the product range also includes higher pressure classes. Final selection should be based on the applicable piping and steam-system requirements.

The listed desuperheater products are temperature rated up to 1200°F (650°C). Actual application suitability depends on the steam conditions, installation arrangement, control-water supply, and selected product design. B-Tech Valve can provide application guidance for fixed spray-ring and variable probe-type configurations.

The SPAD is a small-pipe attemperator desuperheater using a fixed-nozzle spray ring that clamps between two steam pipe flanges. The LPD is a large-pipe, probe-type desuperheater with a variable-nozzle, fully actuated control valve and 90° flanged insertion for steam pipes 6 inches and larger.

The SPAD and Steam Attemperator designs are fed water from a separate temperature control valve. This arrangement supports spray-ring steam conditioning within the piping system. The required water-control arrangement and product sizing should be reviewed against the customer's steam conditions and process requirements.

Yes. The Steam Attemperator is sized for each customer's application, and B-Tech Valve positions its products as application-sized steam and gas desuperheater and attemperator valves. Customers should provide relevant steam piping, operating, temperature, pressure, and control requirements so the appropriate design can be evaluated.

The listed applications include power plants and process plants. These facilities use desuperheaters to condition steam, improve heat-transfer capability, protect piping and downstream equipment, support steam flow, and reduce boiler loads. Product selection can include fixed spray-ring or variable probe-type designs based on line size and system requirements.
