OVERVIEW & BENEFITS
The 1/2″ Thermal Relief Valve (Model 85.300.024BEP) is designed to prevent overheating in high-pressure pump systems during bypass mode. When water inside the pump reaches approximately 145°F, this thermal valve opens to discharge hot water and allow cooler water in, protecting your pump seals and components.
