Suttner ST-5 Vertical Mount Flow Switch – 8 GPM for Hot Water Pressure Washers

Suttner ST-5 Vertical Mount Flow Switch – 8 GPM for Hot Water Pressure Washers

Control your hot water pressure washer burner with the Suttner ST-5 Flow Switch. Designed for vertical mounting, this flow-activated switch detects water movement through the pressure washer system and can be used to control the burner circuit.

When adequate water flow is present, the switch allows the burner system to operate. When water flow stops, the switch changes state to shut the burner down, helping protect the heating coil from excessive heat.

What it does:

The ST-5 senses water moving through the pressure washer plumbing. When sufficient flow is detected, the switch activates the electrical circuit used to control the burner. When the trigger gun is released and water flow stops, the switch shuts the burner circuit down.

Why it matters:

A properly functioning flow switch helps prevent:

• Burner operation without adequate water flow

• Overheating of the heating coil

• Excessively high water temperatures

• Intermittent burner operation

• Premature heating system damage

The Suttner ST-5 is an excellent choice when you need reliable water-flow-based burner control for a commercial hot water pressure washer.
