I've got a 4500 psi belt drive machine with a Cat pump. The unloader gave out and this was a perfect replacement and the price was right.

I put it on a 4400 psi Harbor freight Pressure Washer works great now when we’re working if we need to let the Pressure Washer run for a couple minutes without turning it off, I don’t have to worry about burning it up off the unloader ran a water hose I can either run it out somewhere Water go or back into a tank so I’m not wasting water

VRT3 Unloader Turned My Pressure Rig from Meltdown Machine to Zen Master
Style: With Knob
Size: 4500 PSI
Color: Black
As the owner of a pressure cleaning company here in Florida (where every job is 90% humidity, 10% actual cleaning, and 100% swearing at equipment), I finally upgraded to this Comet VRT3 unloader valve after my old one decided to throw a tantrum and leak like a politician's promises. This bad boy is a 4500 PSI, 10.5 GPM beast with 3/8" FNPT ports all around (inlet, outlet, bypass) and that classic black knob for easy adjustment. Installed it in about 10 minutes—no special tools, no blood sacrifices—and suddenly my pump isn't screaming every time I ease off the trigger. It unloads pressure smoothly, responds to flow changes like it's reading my mind, and the EZ-start feature means my trigger gun doesn't feel like it's arm-wrestling a gator anymore. No more constant cycling, no more random pressure spikes that make the wand buck like a caffeinated bronco, and zero leaks after weeks of blasting mildew off walls and driveways in 95-degree swamp heat. My crew even stopped asking "is the machine dying again?" because... it's not. It's just vibing. If you're tired of your pressure washer acting like a toddler on a sugar high, this VRT3 is the adult in the room. Solid brass build (feels premium without the premium price), reliable bypass, and it handles hot or cold water like a champ. Worth every penny—my old unloader is now in timeout in the parts bin. Would buy again.
