The Interpump H450 Unloader Valve is a heavy-duty brass pressure regulating valve designed for high-performance pressure washing and industrial cleaning systems. It helps protect the pump by diverting water flow during bypass operation while maintaining stable system pressure. 

With a maximum flow rate of 50 L/min, operating pressure up to 400 bar, and a maximum temperature of 80°C, the H450 is ideal for demanding high-pressure applications. It features a 1/2" female inlet and 1/2" male outlet for compatibility with larger-capacity systems.
