91000XT Series Tank Thermostat
Brand: Trerice Gauges & ValvesThe 91000XT Tank Thermostat is specifically designed to control the temperature of heaters, treaters and separators within the petroleum industry.
It is entirely self-contained, requires no external power source, and is the most widely preferred unit of its kind.
When installed in a treater, the fail-open valve will automatically close-off the flow of gas as temperature increases, thereby regulating temperature within the treater.
The Trerice 91000XT is ruggedly constructed with a heavy duty, die cast aluminum actuator housing and fully enclosed bellows assembly.
Its single seated, cast-iron valve body is fitted with a stainless steel plug assembly and soft seating Viton O-ring to provide tight close-off.
