Heated pressure regulation that helps protect gas sample integrity
The Welker HR Heated Instrument Regulator is a single-stage, spring-loaded, electrically heated pressure reducing valve designed to condition natural gas sample streams before analyzer entry. Installed upstream of an analyzer as a standalone pressure control device or part of a sample conditioning system, the HR provides safe outlet pressure while applying controlled heat to help offset Joule-Thomson cooling, prevent condensation, and maintain sample integrity. With side-entry electric heating, diaphragm or piston sensing, multiple pressure control ranges, body and seat material options, and an ergonomic hand knob, the HR supports reliable analyzer-grade natural gas conditioning.
