100329 Flow Switch with Pilot – 16 GPM, 4000 PSI, 3A 250V for Hot Water Pressure Washers

100329 Flow Switch with Pilot – 16 GPM, 4000 PSI, 3A 250V for Hot Water Pressure Washers

The 100329 Flow Switch with Pilot is a heavy-duty flow-activated switch designed for commercial hot water pressure washer systems. With a capacity of up to 16 GPM and a maximum operating pressure of 4000 PSI, this switch is well suited for larger pressure washer and industrial cleaning systems.

The flow switch detects water movement through the system and provides electrical switching for burner control, helping ensure the burner operates only when adequate water flow is present.

Specifications:

• Part Number: 100329

• Type: Flow Switch with Pilot

• Maximum Flow: 16 GPM

• Maximum Pressure: 4000 PSI

• Electrical Rating: 3 Amp @ 250V

• Application: Hot Water Pressure Washer Burner Control

Applications:

• Hot water pressure washers

• Oil-fired burner systems

• High-flow commercial pressure washers

• Industrial cleaning equipment

• Replacement and custom-built hot water pressure washer systems

Features:

• High-flow design rated up to 16 GPM

• Heavy-duty 4000 PSI pressure rating

• 3 amp @ 250V electrical rating

• Flow-activated switching for burner control

• Helps prevent burner operation without adequate water flow

• Designed for demanding commercial and industrial applications

What it does:

The 100329 detects water flowing through the pressure washer system. When adequate flow is present, the switch changes electrical state to allow the burner control circuit to operate. When water flow stops, the switch changes state again, allowing the burner system to shut down.

Why it matters:

A properly functioning flow switch helps prevent:

• Burner operation without adequate water flow

• Heating coil overheating

• Excessively high water temperatures

• Unnecessary burner operation

• Premature heating system damage

With its 16 GPM capacity, 4000 PSI rating, and 3 amp electrical capacity, the 100329 is an excellent choice for larger commercial hot water pressure washer systems requiring dependable flow-based burner control.
