Description
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. The HR is specifically designed
for use in explosive atmospheres.
