ST-261-I unloader w/ chemical injector 1.8 mm

Features:

Regulating unloader valve

Tamper resistant operator adjustable valve which allows limit setting on both maximum and minimum pressure

Ideal for steam combination applications

Straight flow-through design minimizes pressure loss through valve

Working components constructed of high-grade stainless steel, Teflon, and Viton seals for maximum heat/chemical resistance

Internal bypass valve can be easily accessed and repaired without removing unloader from unit

True to Suttner design tradition, valve is cartridge type and installed in minutes

Pressure adjustment knob can be removed if desired

Specifications:

Downstream injection at 10:1 ratio

Low pressure limit setting eliminates need of additional metering devices

Relies on pressure loss through a restrictive orifice, which is built-in on the st-261. Restriction after the orifice must be minimized in order for injection to occur. Therefore, this system must incorporate a large orifice spray nozzle which reduces such restriction. The usage of a nozzle with a minimum orifice size of 30.0 is recommended. A smaller nozzle could be used, but the added restriction may result in ineffective suction rates or no suction at all. In addition, remember that elbows, fittings, and even hose add to the restriction within the system and may affect or eliminate the suction capabilities.

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!

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.
