VX3-160 | 2320 PSI 303SS Unloader Valve Yellow Spring Head

VX3-160 – Unloader Valve – 2320 PSI – 303SS Yellow Spring

The Annovi Reverberi VX3-160 is a professional-grade unloader valve engineered to provide precise pressure
regulation and dependable pump protection in systems operating up to 2,320 PSI. Built from AISI 303 stainless
steel, it offers excellent corrosion resistance and durability, making it ideal for environments where brass
or plated components fail prematurely. Compact and rugged, the VX3-160 diverts flow into bypass when the spray
trigger is released, protecting pumps, hoses, and fittings from dangerous overpressure.

This model features a yellow spring calibration, ensuring stable, repeatable pressure regulation across a wide
range of cleaning applications. The result is consistent spray performance, reduced pump strain, and reliable
system operation—perfect for contractor rigs, fleet-wash systems, and facility maintenance setups that require
stainless-steel strength with practical ease of use.

Precision Pressure Regulation

The VX3-160 delivers rapid, reliable pressure control to protect system components:

• Prevents Seal Damage – reduces thermal buildup during idle recirculation.
• Extends Pump Life – minimizes stress on pistons, bearings, and valves.
• Protects Hoses & Couplers – prevents sudden pressure spikes.

When the trigger is engaged, pressure builds to the desired level. When released, water is instantly redirected
into bypass, reducing hydraulic and thermal strain on the pump.

303 Stainless Steel Durability

Constructed from AISI 303 stainless steel, the VX3-160 performs reliably in moisture-rich and chemically
exposed environments:

• Corrosion Resistance – maintains integrity in wet or detergent-heavy conditions.
• Durable Performance – withstands heavy cycling in contractor or facility wash systems.
• Professional Grade – outperforms lower-grade brass components.

For marine, chemical wash, or high-moisture environments, stainless steel construction ensures minimal wear and
long-term reliability.

Yellow Spring Calibration

The VX3-160’s yellow spring is tuned for medium-pressure use (2320 PSI), providing:

• Consistent Regulation – predictable and stable output pressure.
• Smooth Bypass Action – reduces hose whip and operator fatigue.
• Balanced System Performance – ideal for daily contractor and light-industrial use.

Color-coded springs allow quick identification of calibration levels, reducing setup mistakes and speeding
maintenance.
