Overview

The UV-VRT3-310-EZ is a pressure washer unloader valve with an easy-start feature, rated to 4500 PSI and 10.5 GPM. When you release the trigger gun, the valve diverts water into bypass instead of dead-heading the pump; the easy-start design also bleeds off pressure so the engine pulls over with less resistance on startup. An adjustment knob gives you variable pressure control, so you can dial output down for lighter work. Plumbing is 3/8″ throughout — two 3/8″ female inlets, a 3/8″ outlet, and two 3/8″ female bypass ports — and it handles water up to 194°F, so it works on hot-water machines as well as cold.

Frequently asked questions

The easy-start feature bleeds pressure off the pump when the machine is shut down, so the engine turns over with less resistance the next time you start it. This is especially useful on pull-start gas pressure washers, where trapped pump pressure makes the recoil hard to pull.

It fits machines running up to 4500 PSI and 10.5 GPM with 3/8″ plumbing — two 3/8″ female inlets, a 3/8″ outlet, and two 3/8″ female bypass ports. Match your pump's pressure, flow, and port sizes before ordering; if you're not sure, call us with your pump model.

Yes — it has an adjustment knob for variable pressure control, so you can turn output down for lighter-duty surfaces and back up for full pressure. Never adjust it above your pump's rated pressure.

Yes, it is rated for water temperatures up to 194°F, which covers most hot-water pressure washers. Verify your machine's output temperature stays at or below that rating.
