DESCRIPTION
Automatic Thermal Protection for Pressure Washer Systems
The 1/2" MNPT 2,000 PSI 62.7°C / 145°F Thermal Valve provides reliable overheat protection for pressure washer pumps and systems. Designed to automatically release hot water when temperatures reach 62.7°C (145°F), this valve prevents pump damage caused by recirculating heated water during bypass or idle operation. By maintaining safe operating temperatures, it ensures long-term performance and efficiency for your equipment.
Reliable Protection Against Overheating
When your pressure washer runs in bypass mode, water can quickly heat up within the pump, leading to seal and component failure. This thermal relief valve activates automatically at the preset temperature, releasing overheated water to allow cool water to enter. The result is consistent protection that extends pump life and reduces maintenance costs.
Heavy-Duty Brass Construction
Constructed from high-quality brass and stainless steel components, the 1/2" MNPT Thermal Valve is built for durability and dependable performance under continuous use. Rated for pressures up to 2,000 PSI, it resists corrosion, heat, and wear, making it ideal for demanding residential, commercial, and industrial cleaning applications. The 1/2" MNPT male threads provide a secure, leak-free fit compatible with standard pump outlets and fittings.
Easy, Maintenance-Free Operation
Compact and simple to install, this thermal valve requires no tools or adjustments. It resets automatically once the water cools, delivering continuous protection without manual intervention—keeping your pressure washer ready to perform at all times.
