The Interpump H253 Unloader Valve is a stainless steel pressure regulating valve designed for professional and industrial pressure washing systems. It protects the pump by diverting water flow during bypass operation, helping to maintain consistent pressure and reduce component wear. 

Suitable for flow rates from 8 to 30 L/min, the H253 operates at pressures up to 250 bar and temperatures up to 80°C. It features a 3/8" female inlet and 3/8" male outlet, making it compatible with a wide range of high-pressure cleaning equipment.
