Thermal Valves

Industrial Duty Thermal Valves for Heat Build-Up Protection
Photo of Thermal Valves

A Thermal Valve is used to eliminate heat build-up in a closed loop by-pass system when liquid is being returned to the pump inlet. Thermal Valves can only be installed when there is a pressurized pump inlet. During recirculation of by-pass liquid, the thermal valve will detect temperature rises in the liquid. If the set temperature is reached, a bleed port dumps a portion of the over-heated fluid.

Light-weight and easy to install, three different inlet port sizes are available: 1/4”, 3/8” and 1/2” NPTM.

Product Range:
Up to 25 GPM, up to 125 PSI, temperatures 130°F, 145°F, 165°F, 180°F and 190°F 

Typical Usage:
Used on systems that can be run in full by-pass for an extended period of time, and have a pressurized inlet. Most commonly found on portable high-pressure wash systems.

Materials:
Brass or reinforced composite.
