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.
Swagelok RHPS series deliver precise pressure control in process fluid systems up to 4 in. (101 mm) in a variety of spring-, dome-, and air-loaded pressure regulators.
A pressure regulator has a sensing element (piston or diaphragm) which, on one side, is subjected to a load force (FS) created by a spring (as shown below) or gas pressure. On the other side, the sensing element is subject to the force (F) of the system fluid.
