Welker Instrument Regulators

ISD Instrument Regulator

The Welker I-Series Instrument Regulators maintain downstream pressure control in analytical, process, sampling, or injection systems to protect sensitive equipment from costly damage. These instrument regulators are spring-loaded pressure-reducing valves designed to reduce a higher pressure filtered pneumatic supply to a lower outlet pressure safe for downstream instrumentation.

Features & Benefits

  • Compact Design
  • Multiple flow coefficients and pressure control ranges
  • Port configuration Options
  • All 316/316L Stainless Steel Body and Trim
  • Knurled spring housing
  • Suitable for small enclosures and panel mounting
  • adaptable to pressure requirements of downstream equipment
  • select accessory arrangement best suited for the installation and application
  • prevent hand slippage during maintenance
  • Uncomplicated maintenance require no special tools and little downtime

IRD Probe Regulator

The Welker Original IRD Probe Regulator delivers a continuous supply of representative samples to an analyzer at the appropriate pressure for
real-time natural gas analysis of high-volume lines.

Features & Benefits

  • Fixed insertion length
  • Pressure-regulating probe tip with thermal fins
  • Low internal volume
  • Multiple pressure control ranges
  • Welker Spring Range Kit (IRD-4SS option)
  • Collect representative samples from the center one-third of the pipeline
  • Regulation point in the pipeline
  • Mitigate the Joule-Thomson effect and prevent sample condensation
  • Reduced lag time
  • Real-time sample analysis
  • Adaptable to pressure requirements of downstream analyzer
  • Easily swap springs to change the output pressure range for a new application or downstream device (IRD-4SS option)

IRA-4SS Probe Regulator

The Welker IRA-4SS Probe Regulator is designed to regulate a gas sample stream to an analyzer without interrupting pipeline flow.
With AI Control™, the probe automatically inserts and retracts using pipeline pressure.

Features & Benefits

  • Provides properly conditioned sample stream
  • Insert and retract probe at full pipeline pressure
  • Easily adjustable to multiple insertion depths
  • Point of regulation occurs at the tip of the probe in the flowing stream
  • Probe design inhibits creation of free liquids and mitigates the Joule-Thomson effect
  • Diaphragm design for optimizing low-pressure output sensitivity
  • Proven safety with AI Control™ provides peace of mind
  • Reduces line pack for analyzer applications
  • Probe retraction design allows maintenance to be performed during continuous pipeline operation
  • Design allows for easy installation and intuitive operation
  • Transferable from location to location
