PS6010 Pressure Switch 1/4 Inch | 2.5 GPM 4060 PSI

PS6010 Pressure Switch 1/4 Inch | 2.5 GPM 4060 PSI

The PS6010 pressure switch is a heavy-duty brass pressure switch assembly
manufactured by Annovi Reverberi (AR North America) for use in professional
hot-water pressure washer systems. It is designed to monitor discharge
pressure and translate hydraulic demand into a simple electrical on/off signal
used for burner control, coil protection, and system bypass logic. With a
maximum system rating of 4,060 PSI, a compact 1/4″ male pressure
connection, and a robust mechanical design, the PS6010 is widely used by OEM
equipment builders and service technicians who require consistent, repeatable
pressure-based control in harsh wash environments.

At the heart of the PS6010 is a mechanical diaphragm linked to an internal
micro-switch. When system pressure rises above the factory-set activation point
of approximately 363 PSI, the diaphragm deflects and actuates the electrical
contacts. This change in state is typically used to enable a burner, heating
coil, or control relay. When pressure drops below the setpoint, the switch
returns to its normal position, signaling the control system to shut down the
burner and redirect flow through bypass. This simple but proven approach makes
the PS6010 extremely reliable in real-world hot-water applications.

• Brass pressure switch designed specifically for hot-water pressure washer systems.
• Rated for up to 4,060 PSI maximum working pressure.
• Activation point of approximately 363 PSI for dependable demand sensing.
• 1/4″ male process connection for compact installation.
• 250 V AC, 16 A electrical rating with integrated molded cable.

How the PS6010 Works in a Hot-Water Pressure Washer

In a typical hot-water pressure washer, the PS6010 is installed in the high-pressure
discharge line downstream of the pump and upstream of the heating coil or burner
control circuit. The switch does not regulate pressure mechanically; instead, it
monitors pressure and converts that information into an electrical signal
used by the control system.

When the operator pulls the spray gun trigger, water begins flowing through the
system and pressure rises above the activation threshold. At this point, the
internal diaphragm moves, closing or opening the micro-switch contacts depending
on wiring configuration. This electrical signal allows the burner to fire and
heat the water as it passes through the coil. When the trigger is released,
system pressure drops, the switch returns to its rest state, and the burner is
disabled. Water is then routed back through the unloader or bypass loop, keeping
the system safe and preventing overheating.

Typical Operating Sequence

• Gun open (demand on): Pressure rises above ~363 PSI, the switch changes state, and the burner or heating circuit is enabled.
• Gun closed (demand off): Pressure drops below the setpoint, the switch resets, and the burner is shut down.
• Automatic response: Each trigger pull or release causes the PS6010 to respond instantly to pressure changes without manual reset.

Construction, Materials, and Performance Ratings

The PS6010 is built to withstand the demanding conditions found in commercial and
industrial wash equipment. Its solid brass body provides excellent resistance
to corrosion, vibration, and pressure spikes. Brass is particularly well suited
to hot-water environments, where temperature fluctuations and moisture exposure
are common.

Inside the switch, the diaphragm and micro-switch assembly are engineered for
long service life under repeated cycling. Unlike electronic sensors, the PS6010
relies on purely mechanical actuation, which reduces complexity and eliminates
the need for calibration or programming. This makes it especially attractive for
equipment that must remain serviceable in the field with minimal downtime.

• Maximum system pressure: 4,060 PSI (280 bar).
• Activation pressure: Approximately 363 PSI.
• Electrical rating: 250 V AC, up to 16 amps.
• Maximum fluid temperature: Approximately 167 °F (75 °C).
• Cable length: Roughly 45 inches for flexible routing inside equipment enclosures.

Design Advantages

• Durable all-brass hydraulic body for long-term reliability.
• Compact footprint allows installation close to the pump or heating coil.
• Simple on/off electrical contacts compatible with relays and burner controls.
• No electronics or software, reducing failure points in harsh environments.

Role in Hot-Water System Control and Safety

In hot-water pressure washer systems, pressure switches like the PS6010 play a
critical role in system balancing and safety. Coordinating burner operation
with actual water demand helps prevent dangerous conditions such as overheating,
dry firing, or excessive fuel consumption. By ensuring that the burner only fires
when water is flowing and pressure is present, the PS6010 protects both the
heating coil and surrounding components.

The switch also contributes to efficient bypass operation. When the spray gun is
closed, the system immediately signals the burner to shut down and routes water
back to bypass, reducing thermal stress and minimizing scale formation inside the
coil. This improves overall system longevity and helps maintain consistent
performance over time.

• Synchronizes burner firing with operator demand.
• Reduces fuel waste and unnecessary heat buildup.
• Helps protect heating coils from overheating during bypass.
• Works in conjunction with flow switches, thermostats, and high-limit controls.

Common Integration Scenarios

• Wired in series with a flow switch and thermostat for layered safety control.
• Used as an input signal for burner relays or electronic control boards.
• Installed in cabinet units, trailer-mounted skids, and wall-mounted washers.

Typical Applications

Thanks to its pressure rating, compact connection size, and compatibility with
hot-water systems, the PS6010 is suitable for a wide range of professional cleaning
applications. It is commonly specified as original equipment or as a direct
replacement in systems using AR pumps and accessories, as well as many compatible
third-party machines.

• Hot-water pressure washers used in commercial and industrial cleaning.
• Industrial wash bays for equipment, vehicle, and facility cleaning.
• Fleet and truck wash systems servicing delivery and utility vehicles.
• Food and beverage washdown systems with properly rated components.
• OEM-built cleaning equipment requiring reliable pressure-based burner control.
