ThermOmegaTech® Thermostatic Drain Valve for Locomotives Magnum GURU®

Operation The Magnum GURU® Plug is a higher discharge capacity version of the standard GURU® Plug. The Magnum GURU® Plug is a self-operating thermostatic drain valve that responds to engine coolant temperature and will pop open and drain when coolant reaches the setpoint (35°F or 40°F). This provides almost a full 1.2 inch bore to rapidly drain a locomotive before freeze damage can occur. Benefits Drains twice as fast as the standard GURU® Plug Will not trip or dump while locomotive is running Straight SAE threads and O-ring seals provide for easy field maintenance and testing Easy installation Completely mechanical – No electrical or air connections Not affected by air flow or air temperature surrounding valve – releases only when cooling water reaches setpoint Easy system refill Models available to convert existing freeze protection Slotted actuator feature prevents nuisance dumps when refilling cooling system with cold water Unit automatically rearms after filling and reheating Actuator sensing surface is the only wetted part Optional domed anti-tamper cap eliminates ability to tamper with the valve resetting stem Design Features Actuator sensing surface is the only wetted part Design excludes cooling water chemicals and other debris from moving parts Long service life: All moving parts are stainless steel Available in modified 1-1/4” NPT tee or flanged tee body styles Paint mask minimizes accidental paint-ins Knob on cartridge for easy installation and removal even in awkward locations Applications Locomotive engine cooling systems Stand-by diesel heating circulators Back up protection in event of shutdown On-board tanks and piping
