Natural Gas Sampling: Upstream of an analyzer as a standalone pressure control device or part of a conditioning system
ATEX/IECEx Option: Places where flammable gases are likely to occur in quantities sufficient to cause a fire or an explosion (AKA Ex areas, hazardous locations, hazardous areas, explosive atmospheres)
The Welker HR Heated Instrument Regulator is a single-stage, spring-loaded, electrically heated pressure reducing valve designed to provide an analytical system with a conditioned gas sample stream at a safe output pressure and temperature. The HR’s controlled heating compensates for the cooling brought on by the Joule-Thomson effect to prevent condensation and maintain sample integrity.
