3/8" MNPT 2,000PSI 62.7°C / 145°F Thermal Valve

Automatic Overheat Protection for Pressure Washer Pumps The 3/8" MNPT 2,000 PSI 62.7°C / 145°F Thermal Valve provides critical thermal protection for pressure washer pumps, ensuring your system runs safely and efficiently. This automatic valve releases overheated water once temperatures reach 62.7°C (145°F), allowing cooler water to enter and prevent internal pump damage caused by recirculating hot water during bypass or idle operation. Reliable Heat Regulation for Pump Longevity When your pressure washer is in bypass mode, water circulation can quickly cause heat buildup that threatens seals and pump components. This thermal relief valve activates automatically when needed, maintaining a consistent operating temperature and preventing costly damage. It’s a must-have safety feature for both professional and residential pressure washer systems.
