The Automatic Thermal Relief Valve is a must for any system utilizing a closed-loop bypass line or internal bypass. When the pump is bypassed, the valve protects your pump and accessories against extreme heat.
When the water in the bypass line reaches the valve’s preset temperature, a small amount of hot water is released, which is replaced by cooler supply water.
This, in turn, lowers the temperature of the water in the bypass line, thus signaling the valve to close.
NOTE: The thermal relief valve works most effectively on pumping systems with positive inlet pressures.
