Description
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
