The Interpump K5 Unloader Valve is a high-performance flow-sensitive valve designed for efficient and precise pressure regulation in pressure washing systems. Commonly used on the Cleanwell SS15-100 and HS15-100 Hot Pressure Washers, this versatile valve is ideal for medium to heavy-duty cleaning applications.

The K5 valve features a 200 Bar maximum pressure rating (40 Bar minimum recommended) and supports a flow range of 11-25 Lpm, making it suitable for a wide variety of tasks. Constructed from durable brass and stainless steel, it ensures long-lasting reliability and resistance to wear. The 3/8" BSPF inlet, 1/2" BSPM outlet, and dual bypass connections (3/4" M and 1/2" F BSP) provide seamless compatibility with different systems. Additionally, 1/4" BSPF gauge ports allow for easy pressure monitoring. The K5 unloader valve can be selected in two flow ranges: K5.1 (11-16 Lpm) or K5.2 (16-25 Lpm), allowing you to choose the best fit for your system.
