Product Details
The Interpump K3.2 is a flow sensitive unloader valve designed for small- to mid-sized pressure washer systems requiring reliable automatic pressure regulation. When the spray trigger is released, the valve diverts water back through the bypass, helping protect the pump and improve longevity.
With a maximum pressure rating of 100 Bar and a flow range between 16–21 L/min, this valve is ideal for applications such as light commercial cleaning, mobile detailing, and lower-pressure jetting systems.
The K3.2 features brass construction with stainless steel internals, ensuring dependable operation even in demanding conditions. Fittings include a 3/8" BSPF inlet, 1/2" BSPM outlet, and a dual-size bypass port (3/4" BSPM + 1/2" BSPF). Two 1/4" BSPF gauge ports allow for accurate monitoring of system pressure. Recommended for systems running at minimum 40 Bar pressure.
