Overview

The UV-VRT100-330 is a pressure washer unloader valve rated to 4800 PSI and 26.4 GPM, with a maximum water temperature of 194°F. When you release the trigger gun, the valve diverts water into bypass instead of dead-heading the pump; unloaders like this respond to a rise in pressure or a change in flow, and can also be used for variable pressure adjustment. Plumbing is two 1/2-inch female inlets, two 1/2-inch female by-pass ports, and a 1/2-inch outlet. It uses a blue spring and comes without an adjustment knob. The high flow and pressure ceiling make it a fit for larger triplex-pump machines running high-GPM setups.

Frequently asked questions

It diverts water flow into bypass when the trigger gun valve is closed, so the pump isn't dead-heading against a closed gun. Depending on design, an unloader responds to either a rise in pressure or a change in flow, and it can also be used for variable pressure adjustment.

No, this model ships with no knob. It uses a blue spring, and it can still be used for variable pressure adjustment — just without a hand knob on top.

Yes, the UV-VRT100-330 is rated for water temperatures up to 194°F, so it works on hot-water pressure washer setups within that limit.

Check your port sizes and output: this valve has two 1/2″ female inlets, two 1/2″ female by-pass ports, and a 1/2″ outlet, rated to 4800 PSI and 26.4 GPM. Your machine's pressure and flow should fall within those maximums. If you're unsure, contact APS with your pump model.
