Compact designs

Graham's Steam-Atomizing (SA), Single-Venturi (SV-2), and Double-Venturi (SV-1) styles are available in a variety of configurations to reduce your costs or easily fit into your existing piping.

Standard SA desuperheaters include a replaceable steam-atomizing nozzle, water and atomizing steam piping, a pipe body, and internal nozzle supports. The atomizing nozzle is easily removable.

T-mount SA devices are designed to slide into a tee. They include a replaceable steam-atomizing nozzle, water and atomizing steam piping, and a blind flange. This nozzle is also easily removable.

Standard SV-2 desuperheaters include a venturi water nozzle, water piping, a pipe body, and internal nozzle supports. This design is easily removable.

T-mount SV-2 units are designed to slide into a tee. They are comprised of a venturi water nozzle, water piping, and a blind flange. This design is also easily removable.

Wafer-Style SV-2 units are "sandwiched" between two flanges. Components include a venturi water nozzle, water piping, and a flat, doughnut-shaped wafer. The nozzle is centered in the wafer, with supports to hold it in place.

Double-Venturi SV-1 desuperheaters rely on two venturis for successful operation – the nozzle venturi and the body venturi. These designs are installed directly in between two standard flanges. No special piping items are necessary.
