Product Details
The Interpump K3.1 is a flow sensitive unloader valve engineered to regulate system pressure and protect pressure washer pumps in lower flow setups. Designed for smaller jetting systems and mobile washers, it automatically diverts water to bypass when the spray trigger is released.
This unit supports up to 100 Bar pressure and a flow rate between 11–16 L/min, making it ideal for compact pressure cleaning units. The robust brass body with stainless steel internal components ensures durability, even under frequent cycling.
Featuring a 3/8" BSP female inlet, 1/2" BSP male outlet, and a dual bypass port (3/4" BSP male + 1/2" BSP female), the K3.1 is compatible with a wide range of plumbing setups. It also includes two 1/4" BSPF gauge ports for monitoring system performance. For optimal function, a minimum working pressure of 40 Bar is recommended.
