Overview
Hale’s Thermal Relief Valve automatically protects your pump from the overheating that may be caused by “deadheading”. Minimizing the need for operator attention to overheating during pumping operations, the TRV 120 automatically dumps a controlled amount of water to atmosphere or back to tank when the pump water temperature exceeds the preset value (120oF/49oC) of the relief valve, and then automatically closes when the water cools. When ordered as a TRV-L 120 with indicator light option, a visual warning lamp is lit when the TRV valve is open. The TRV-L 120 combines the functions of water bypass with an operator warning system
