The Suttner ST-261 Unloader Valve is a high-performance pressure regulating valve designed to protect pumps and control system pressure in high-pressure cleaning setups. Operating between 500 and 3625 PSI, this unloader diverts water flow when the trigger gun is closed, ensuring the pump runs safely under bypass conditions.
Engineered for reliability, the ST-261 handles flow rates up to 8 GPM and temperatures up to 176°F. Its robust construction and compact design make it ideal for commercial and industrial pressure washers. Equipped with 3/8\\” FPT inlet and outlet ports, it integrates easily with most standard pressure washer configurations.
