Suttner ST261 Unloader Valve

The Suttner ST261 Unloader valve is a great choice for most machines under 8GPM. This unloader can be panel mounted. Unloader valves are used for adjusting or setting the pressure on your pressure washer to prevent damage to your pump or surfaces you may be cleaning. This unloader is available in 3 variations, the standard ST261, the ST261 with built in chemical injector, and the ST261 with tamperproof pressure adjustment.
