K7 Unloader

K7 Unloader

The K7 is a flow-actuated unloader made for systems running between 6.6 and 10.0 GPM, with a max pressure rating of 3500 PSI. It’s built with a balanced piston that helps keep pressure steady and easy to control. Since there are no external springs or moving parts, you don’t have to worry about things breaking or wearing out too fast.

It also uses brass and stainless steel inside, which helps it hold up better over time especially if you're using it often. The design makes pressure adjustment smooth and reliable, and it responds well when water flow changes. You’ll get consistent performance without the pressure spikes or hiccups that cheaper unloaders can cause.

If you're looking for something simple, tough, and easy to maintain, the K7 is a solid choice. It gives you dependable pressure control without the extra hassle, which means less downtime and more time getting jobs done.
