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 misting 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, two different inlet port sizes are available: 1/4” and 3/8” MNPT x 1/8″ FNPT drain port.
