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

CONVENIENCE EASE OF OPERATION
Insert and retract the probe at full pipeline pressure simply by turning four valves.
REGULATION THE PROCESS
The point of regulation and mitigation of the Joule-Thomson effect occur at the probe tip in the flowing stream.
PRECISION DIAPHRAGM DESIGN
The diaphragm design in the regulator optimizes low-pressure output sensitivity.
