AR52184 | VB40/10000 Unloader, 10000 PSI, Stainless

The AR52184 – VB40/10000 Unloader Valve is one of the most robust,
extreme-duty unloaders in the Annovi Reverberi catalog. Built from stainless steel
and rated for operating pressures up to 10,000 PSI, it is designed
to regulate and protect ultra high-pressure cleaning systems used in hydro blasting,
marine maintenance, refinery work, and other heavy industrial applications where
safety, durability, and reliability are critical.

When spray flow is interrupted, the VB40/10000 automatically diverts water to bypass,
preventing catastrophic overpressure that can damage pumps, burst hoses, or compromise
fittings. This fast, automatic protection is essential in systems that operate far
beyond conventional pressure washer ranges.

Engineering & Construction

• All-stainless-steel body resists corrosion, scaling, and chemical attack in harsh environments such as shipyards, refineries, and chemical plants.
• Reinforced housing and internals are engineered for ultra high-pressure use, withstanding extreme cyclic loads and vibration without fatigue.
• Heavy-duty sealing system maintains leak-free performance under constant cycling at 10,000 PSI.
• Precision machining ensures smooth bypass transition and consistent regulation where standard valves cannot operate.

Functional Advantages

• Ultra high-pressure regulation for systems operating up to 10,000 PSI, ideal for hydro blasting and extreme-duty cleaning.
• Automatic bypass operation instantly redirects flow when the spray is stopped, protecting pumps, hoses, and operators from dangerous pressure spikes.
• Continuous-duty reliability for rigs that run long hours in punishing conditions without sacrificing performance.
• Heat and vibration resistance allows dependable service in hot, abrasive, and high-shock industrial environments.
• Low maintenance stainless construction and robust seals extend service intervals and reduce downtime.

Installation & Service Notes

• System compatibility: for use only with ultra high-pressure pumps, hoses, and accessories rated to 10,000 PSI—verify all components before installation.
• Professional connections: machined ports provide secure fitment in hydro blasting and industrial wash systems.
• Adjustable setting: allows technicians to fine-tune working pressure while preserving safe relief margins.
• Shipping: typically ships within 24–48 hours via UPS Ground in normal seasons; allow 2–3 additional days during peak demand.

Applications

• Hydro blasting: surface prep, paint and rust removal, and heavy descaling at shipyards, refineries, and construction sites.
• Marine cleaning: hull, propeller, and offshore equipment washing where extreme pressure is required for marine growth removal.
• Refinery & petrochemical maintenance: tank, reactor, and pipe cleaning to remove hardened deposits and scale.
• Industrial degreasing: stripping baked-on oils, grease, adhesives, and byproducts in manufacturing plants.
• Municipal & infrastructure projects: hydro demolition, concrete surface prep, bridge and tunnel cleaning.
