The CAT Pumps 7177 Thermal Valve is designed to eliminate heat build-up in closed loop pumping systems. The valve is mounted in the bypass line of the pressure regulating device when the by-pass liquid is being recirculated to the inlet of the pump. This is a cost-effective way to protect pumps from excessive heat.
