Product Details
The Interpump K1 Unloader Valve is a heavy-duty flow-sensitive pressure regulation valve engineered for high-performance pressure washers and industrial cleaning systems. Capable of handling up to 250 Bar and flows between 9–41 litres per minute, it ensures safe and efficient operation by smoothly diverting water to bypass when the trigger is released.
Manufactured with a brass body and stainless steel internal components, the K1 offers excellent resistance to pressure wear and water corrosion. It features a 3/8" BSPF inlet, a 1/2" BSPM outlet, and a 1/2" BSPM bypass, making it versatile for integration into professional setups. Dual 1/4" BSPF gauge ports are included for precise monitoring and maintenance.
A minimum operating pressure of 40 Bar is recommended for consistent performance. This unloader is suitable for static or mobile washdown systems, drain jetting units, and commercial pressure washers.
