RegulatorsTrerice 91000, 91400, 91600 Self-Operated Temperature Regulator
The Trerice 91000, 91400, and 91600 self-operating temperature regulators do not require an external power source, and are preferred by original equipment manufacturers (OEMs), mechanical contractors, and specifying engineers. The actuator has a rugged die-cast aluminum housing, fully enclosed bellows assembly, and internal over range protection. The valve bodies for the 91000, 91400, and 91600 models are offered in single-seated, double-seated, and three-way designs. The 91000, without idicating actuator dial, features a lower profile for applications with space constraints. The 91400, with indicating actuator dial, allows the operator to verify the process temperature. The 91600, with fail-safe actuator, causes valve to fail in the safe control position should accidental damage to the thermal system occur.

RegulatorsTrerice 91000XT Self-Operated Tank Thermostat Temperature Regulator, OTTR (Oil Treater Temperature Regulator)
The Trerice 91000XT tank thermostat is a temperature regulator specifically designed to control the temperature of oil field heaters, OTTRs (oil treater temperature regulators), and separators. 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 normally open valve will automatically close off the flow of gas as temperature increases, thereby regulating temperature within the treater. The 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 shut-off.
