Swagelok® Pressure-Reducing Regulators, Electrically Heated

KEV electrically heated vaporizing pressure-reducing regulators are rated for use in hazardous areas and can vaporize liquid samples or preheat gas samples to prevent them from condensing.

Request More Information

The KEV series regulators feature a heating element that is in direct contact with the process fluid for maximum thermal efficiency and is removable for easy cleaning. It can be mounted horizontally or vertically and the one-piece body eliminates potential leak paths.

KEV series regulators are ATEX, IECEx, and CSA certified for critical/hazardous environments as listed in the product catalog and have a T3 temperature classification for all heater ranges.
