Suttner ST-5VH Vertical & Horizontal Flow Switch – 5000 PSI for Hot Water Pressure Washers

Suttner ST-5VH Vertical & Horizontal Flow Switch – 5000 PSI for Hot Water Pressure Washers

The Suttner ST-5VH Flow Switch provides reliable water-flow sensing for hot water pressure washer burner control systems. Unlike flow switches that require a specific mounting orientation, the ST-5VH is designed for both vertical and horizontal installation, providing greater flexibility when space and plumbing configurations are limited.

Rated for pressures up to 5000 PSI, this heavy-duty flow switch is an excellent choice for commercial and industrial hot water pressure washer systems.

Specifications:

• Brand: Suttner

• Model: ST-5VH

• Type: Flow Switch

• Maximum Pressure: 5000 PSI

• Mounting: Vertical or Horizontal

• Application: Hot Water Pressure Washer Burner Control

Applications:

• Hot water pressure washers

• Oil-fired burner systems

• Commercial cleaning equipment

• Industrial pressure washing systems

• Replacement and custom-built hot water pressure washer systems

Features:

• Can be mounted vertically or horizontally

• Heavy-duty 5000 PSI pressure rating

• Senses water flow to control burner operation

• Provides automatic burner control as water flow starts and stops

• Helps protect the heating coil from excessive temperatures

• Flexible mounting makes installation easier in tight equipment layouts

• Built for demanding commercial pressure washer applications

What it does:

The ST-5VH detects water movement through the pressure washer system. When adequate flow is present, the switch activates the burner control circuit. When water flow stops, the switch changes state and shuts the burner down.

Why it matters:

A properly operating flow switch helps prevent:

• Burner operation without adequate water flow

• Heating coil overheating

• Excessively high water temperatures

• Unnecessary burner cycling

• Premature heating system damage

The ability to install the ST-5VH either vertically or horizontally makes it an especially versatile replacement flow switch for hot water pressure washers where plumbing layout or available space can make installation challenging.
