Overview

Interpump K7 flow sensitive unloader valve in brass and stainless steel, rated to 200 bar and 25 to 41 litres per minute, with water up to 60°C. It regulates and limits system pressure by diverting excess water to the bypass, and releases the flow fully when the outlet is closed. Pressure is adjusted by hand.

It has a 3/8" BSP female inlet, 3/8" BSP male outlet, 3/8" BSP female bypass ports and 1/4" BSP female gauge ports.
