ThermOmegaTech’s line of GURU PC® Valves are self-operating, thermostatic drain valves that protect potable water bearing systems on passenger cars from freezing which in turn protects your investment and keeps your equipment safe.

The advanced, reliable GURU PC® valves increase uptime on passenger cars by preventing water lines from freezing before any damage can occur.

The GURU PC® ¾” and 1″ valves monitor ambient temperatures and will automatically drain the water tanks if the air temperature falls to the valve’s set-point, 35°F, preventing burst piping and frozen tanks. Completely mechanical, with no outside power required, its high flow design allows for rapid draining, eliminating costly freeze damage.

An electric heater is available to allow for quick refilling of the water system to get the passenger car back into service as soon as possible.

GURU® Plug Rebuild Program

ThermOmegaTech® now offers a rebuild program which allows you to return your old GURU® valves to be rebuilt so you essentially get back a brand new valve! To learn more visit our Rebuild Program page.
