The IBR model in Welker’s I-Series Instrument Regulators is a standalone, spring-loaded, piston-sensing back-pressure regulator suitable for controlling gases and low-viscosity liquid products. By controlling its inlet pressure, the IBR helps to balance system pressure and product flow.

The Welker Automatic Insertion Temperature Probe is designed for use in operations where it is necessary to determine pipeline temperature for measurement or analysis. The design of the unit allows the operator to control the movement of the probe into and out of a pressurized pipeline safely by utilizing pipeline pressure and manipulating four valves. […]

The ISPE model in Welker’s I-Series Instrument Regulators is a cost-effective, standalone piston-sensing instrument regulator suitable for regulating air and light gases, such as hydrogen. With global and industrial decarbonization goals, the development and deployment of hydrogen and fuel cell technologies are growing in importance. Welker’s ISPE Instrument Regulator can be used across the hydrogen […]

For real-time natural gas analysis of high-volume lines, you need a sample probe that can deliver a continuous supply of representative samples to your analyzer at the appropriate pressure. The Welker Original IRD Probe Regulator mounts directly to a hot tap or mating flange on your depressurized pipeline and has a fixed insertion length to […]

Is there something in the air? You may be in an explosive atmosphere. Knowing these hazardous locations require specially designed equipment to reduce the risk of fires and explosions, Welker updated the design of its patented HR-4SS Heated Regulator specifically for this purpose. The Welker HR Heated Instrument Regulator is a single-stage, spring-loaded, electrically heated […]
