The 1" GURU PC® is a thermostatic drain valve for potable water systems in passenger rail cars, designed to automatically drain water before freeze damage occurs using a mechanical thermal actuator without requiring electrical or air connections. It is constructed of low lead brass and bronze, features dual port seals, and is inline serviceable. The valve has a 1" NPT connection, operates at up to 120 PSIG, and functions within a temperature range of 1.7°C to 7°C, with storage temperatures from -55°C to 71°C. It is NSF/ANSI/CAN 61 and 372 certified and shock and vibration tested. The device measures 11.1 cm in length, 14.3 cm in height, and 4.8 cm in width, and weighs 1.9 kg. Heater assemblies are available as optional add-ons for 120VAC/74VDC or 230VAC operation, but are not part of the base valve unit.
The 1″ GURU PC® valve is self-contained and drains water bearing systems automatically before freeze damage can occur by monitoring ambient temperatures. Freezing conditions, which put water tanks and piping at risk for freeze damage, occur when the car heat is turned off for switching locomotives or even brief layovers. Since the valve is completely mechanical, no electrical or air connections are required. When used with the heater assembly, we provide a 5 foot (1.5m) cable and wiring diagram for hard wiring, or any various plug of your choice.
