ThermOmegaTech’s GURU® Valves are self-operating, thermostatic drain valves that protect locomotives from freeze damage which in turn protects your investment and keeps your equipment safe.
The advanced, reliable and compact self-contained GURU® valves increase uptime on locomotives by preventing water lines from freezing before any damage can occur.
The GURU® DL2.1 and Magnum locomotive valves are water-sensing, self-operating thermostatic drain valves that respond to engine coolant temperature. When the locomotive is shut down and cooling water reaches the temperature set point of the valve, the plug will snap open draining the locomotive cooling system before any freeze damage occurs.
The Magnum GURU® Plug is capable of providing a higher discharge capacity than the standard GURU® Plug. With an almost 1.2 inch bore, the Magnum GURU® drains twice as fast as the standard GURU® Plug, guaranteeing rapid drainage of the locomotive.
The GURU® DL2.1 CH and CHS Plugs are automatic drain valves used for water-cooled air compressor head freeze protection. They have almost a full one inch bore to rapidly drain the compressor before damage can occur.
Resetting and rearming any of the GURU® Plugs is easily accomplished by simply reheating the cartridge and utilizing our GURU® Flag and Clip or GURU® Flag and Key tool. These tools allow you to fill a locomotive cooling system with cold water that would otherwise trip the GURU® Plug open.
ThermOmegaTech® also offers a system flushing attachment, CHCT. The compressor head-cleaning tool allows insertion of the cleaning nozzle into the same flanged body as the GURU® Plug Type CH or CHS to flush the system and clean out any dirt or contaminants.
ThermOmegaTech® offers a Rebuild Program to send in your old GURU® Plugs to be cleaned, some components replaced, and the valve rebuilt & retested. This program is offered for both our Locomotive and Passenger Car valves.
