K5.1E flow actuated unloader 3.0-4.2 GPM 1450-3000 psi.

 The unloader valve diverts water flow into bypass when the trigger gun valve is closed. Flow actuated unloaders divert water to the bypass when there is a sufficient reduction or stoppage of water flow. The flow actuated unloader has an orifice instead of a check valve in pressure actuated unloaders. When the gun valve is closed and water flow stops, system pressure is increased rapidly at all points past the orifice. A small channel in front of the orifice allows the increased pressure to travel up to the piston assembly, pushing it down. The rest of the water flow is diverted through the bypass and back to the float tank or pump inlet.

 Features:

  • Features all stainless and brass internal parts.
  • No external moving parts or springs
  • Unique balance nozzle principle eliminates high pressure in all lines while unit is in bypass mode.
  • Eliminates pressure peaks normally generated by conventionally designed unloaders.
  • Unique unbalanced piston design permits precise pressure adjustment.
  • Mounts in discharge line; flow through design
  • Convenient bypass location
  • Dual gauge ports...remember to buy a pressure snubber to ensure a long life for your gauge.

Testimonials

I recently purchased a pressure washer from Pressure Washer Products, and the experience was fantastic from start to finish! The staff is incredibly knowledgeable and helped me find the perfect model for my needs. They answered all my questions and even gave me tips on maintenance and usage. The quality of their products is top-notch.. Highly recommended!

Kerolos Mamdoh

The best pressure washing store hands down. Rex the owner and his team have a wealth of knowledge about the industry. Lori is always there to help you with what you need. I’ve saved alot of money over the years through them because they help to educate you on what products and equipment are best to buy for your specific set up/washing goals. Other places attempt to drain your bank account if you let them. Not here, that’s why they have customers for life

I recently bought a surface cleaner from PWP, and it's been a game-changer. Lori helped me find the right tips for my machine, and the results have been fantastic. Thanks, Lori!

Sheriff Khalifa

Lori was very helpful and got us out surface cleaner and recommended what tips to match our machine. Runs fantastic. She also recommended a chemical injector to try on our trailer and it has been another great upgrade. Lori knows her stuff and the price and shipping was reasonable!

Brent Batton

I am a new customer to this business and have been here three times. Each time I have received fantastic customer service. I am glad there is actually a local business around that deals specifically with pressure washers. Highly recommended.

I love this store. Laurie and Rex/ Family have been a huge help in understanding aspects of the equipment and tools we use in this industry. I’ve learned lots from them. Also the pricing and amount of supplies the store has to offer is perfect for a quick trip to load up and head out.
