pressure reducing regulators dome loaded

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 Regulators

SGRD 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.

SGRD and SHRD Series Features

  • Balanced poppet
  • Diaphragm sensing
  • Non-venting
  • Pilot regulator control

Customizable Features

  • External feedback to pilot
  • Differential pressure pilot (SGRD Series)
  • Dual stage pilot (SGRD Series)
  • Antitamper / factory set pilot handle
  • NACE MR0175/ISO 15156
