Suttner ST-6 Flow Switch – 8 GPM, 4380 PSI for Hot Water Pressure Washers

Suttner ST-6 Flow Switch – 8 GPM, 4380 PSI for Hot Water Pressure Washers

The Suttner ST-6 Flow Switch provides reliable water-flow sensing for controlling the burner on commercial hot water pressure washers. Designed for high-pressure applications, this heavy-duty flow switch is rated for up to 8 GPM and 4380 PSI.

When water begins flowing through the system, the ST-6 activates the burner control circuit. When water flow stops, the switch shuts the burner circuit down, helping prevent excessive heat buildup in the heating coil.
