Trerice 91000 Series Temperature Regulating Valve - Trerice 91000 Series Self-Operating Temperature Regulators are the #1 choice of original equipment manufacturers, mechanical contractors and industrial process engineers. These regulators are the ideal choice for temperature control of industrial equipment, tanks and process streams. The self-operating design provides reliable performance under the most extreme conditions without the need for an external power source.

Valves For 91000 Series

Trerice 91000XT Series Tank Thermostat Valves - The 91000XT Tank Thermostat is especially designed to control the temperature of heaters, treaters and separators.  It is entirely self-contained, requires no external power source, and is the most widely preferred unit of its kind. 
Trerice 91500 Series Pressure Regulating Valves - The Trerice Series 91500  Self-Operating Pressure Regulator is extensively used in canning, meat packing and other food processing industries to regulate pressure cookers, retorts and other devices.  The 91500 requires that a user-supplied pressure sensing line be connected from the downstream controlled point to the regulator’s actuator.  Pressure in this line acts upon the bellows to develop the necessary thrust to stroke the valve. As the downstream pressure increases, the valve closes, thereby reducing the downstream pressure.
Trerice 921 Series Pressure Regulating Valves - The Trerice Series 921 Pressure Regulator is fully self-contained and requires no external power source. This regulator requires that a user supplied pressure sensing line be connected from the controlled point to the diaphragm actuator.  Pressure in this line acts upon the diaphragm to develop the necessary thrust to stroke the valve, thereby maintaining the system at the desired condition.
Trerice 984 Series Pressure Regulating Valves - The Trerice Series 984 Pressure Regulator is an excellent choice for process equipment and service lines with light pressure regulating requirements. It includes a spring-loaded diaphragm that can be externally adjusted by the operator to provide a uniform outlet pressure that is unaffected by normal variations in supply pressure. 
Trerice 988 Series Pressure Regulating Valves - The Trerice Series 988 Pressure Regulator, designed for steam service, provides a sensitive response to reduced pressure changes and delivers the fullest possible volume without an appreciable reduced pressure drop. The 988 includes a spring-loaded diaphragm that can be externally adjusted by the operator to provide a uniform outlet pressure.  It also features a “sensitivity adjuster,” which can be used to eliminate any vibrating or chattering caused by critical flow requirements.
Trerice 1002 Series Pressure Regulating Valves - The Trerice Series 1002 Pressure Regulator is a high capacity pressure reducing valve for water service.  The 1002 has a broad seat opening and is capable of supplying large volumes at reduced pressures.  This regulator is intended for use in a variety of commercial, institutional and industrial applications. It features a bronze or cast-iron body and a stainless steel seat.
