Annovi Reverberi 1/4″ Thermal Relief Valve

The Annovi Reverberi TPP140-1/4A is a high-performance thermal relief valve designed for pressure washer systems, featuring a built-in spray diverter cap for added functionality. This OEM-grade valve is engineered to protect your pump from overheating by automatically venting when water temperatures exceed its rated limit of 140°F. With a maximum working pressure of 200 PSI, it ensures reliable operation under demanding conditions, making it suitable for a wide range of power washer brands.

The valve includes a 1/4″ male inlet connection, ensuring easy integration into most pressure washer pump manifolds. It is mounted on the low-pressure side of the system, where it monitors and regulates temperature to prevent heat damage—a critical feature for extending the lifespan of your equipment. The included spray diverter cap allows for flexible operation, whether you need a directed spray or a broader coverage pattern.
