Swagelok® Pressure-Reducing Regulators, Dome-Loaded
General Industrial (SGRD Series) and High Sensitivity (SHRD Series) pressure-reducing, dome-loaded regulators are suitable for a wide variety of industrial applications where manual or remote operation of the regulator and accurate set pressure control is desired.
Get Help Selecting Process RegulatorsSGRD and SHRD series regulators are engineered for durability in demanding environments. Their bodies are constructed from 316L stainless steel, enhancing corrosion resistance and longevity. These regulators feature internal seals available in various materials, providing improved compatibility with a wide range of chemicals and pressure conditions.
Pressure-reducing, dome-loaded regulators offer superior performance in maintaining stable outlet pressures. By utilizing a pressure dome instead of a set spring for control, these regulators effectively minimize droop. This design ensures consistent outlet pressures, regardless of fluctuations in inlet pressure or flow variations.

Locate detailed product information, including materials of construction, pressure and temperature ratings, options, and accessories.
Caractéristiques : détendeurs ; déverseurs ; modèles à ressort, à dôme, pneumatiques ; raccordement d'extrémité de 1/4 à 4 po ; pressions de service jusqu'à 700 bar (10 150 psig) ; températures de –20 à 80°C (–4 à 176°F)
Un régulateur de pression comporte un élément détecteur (piston ou membrane) qui, d’un côté, est soumis à une force de charge (FS) créée par un ressort (comme sur les schémas ci-dessous) ou par la pression d’un gaz. De l’autre côté, cet élément détecteur est soumis à la force (F) exercée par le fluide du système.
