Valves that are activated by internal measurement and control of fluid temperature are called thermostatic valves.

This type of valve is independent without any external power source.

The operating temperature range is determined by the chemical composition of the wax material and is preset at the factory or local distributor according to the engine or equipment manufacturer’s recommendations.

Once the thermostatic element is calibrated at the set temperature, it cannot be changed unless a new element is installed.

This robust yet simple design prevents operators from accidentally running the equipment too hot or too cold, which leads to higher fuel consumption, costly repairs and breakdowns.

How to use a thermostatic valve

Mixing programs
When valves are used for mixing service, port C is the cold fluid inlet from the cooler, port B is the hot bypass fluid inlet, and port A is the standard outlet.

Port A is the temperature sensing port and mixes hot and cold fluids in the correct ratio to produce the desired output temperature from port A.

Diverting programs

When the valves are used for bypass service, the inlet is port A (temperature sensing port), with port C connected to the cooler and port B to the cooler bypass line.
