DESCRIPTION
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.
Durable Brass Construction for Long-Term Use
Built from premium brass and stainless steel materials, the 3/8" MNPT Thermal Valve is rated for pressures up to 2,000 PSI and engineered for long-lasting reliability. It resists corrosion, wear, and heat exposure, making it ideal for use in tough cleaning environments. The 3/8" MNPT male threading ensures a secure, leak-free fit with standard pressure washer pump outlets and plumbing connections.
Simple Installation and Maintenance-Free Operation
Compact and easy to install, this thermal valve operates automatically—no manual reset or adjustments required. Once the water cools, the valve resets itself, providing continuous protection for your pump system without interruption.
