VHP60 | 8700 PSI High-Pressure Industrial Unloader Valve Valve

VHP60 | 8700 PSI High-Pressure Industrial Unloader Valve Valve

The Annovi Reverberi VHP60 is a heavy-duty unloader valve designed for the most extreme cleaning environments, rated for pressures up to 8,700 PSI (≈600 BAR). This model represents one of the highest-capacity safety and regulation valves in the Annovi Reverberi catalog, engineered to protect pumps and operators from catastrophic overpressure conditions in high-demand industrial systems. With its 1/2F x 1/2F threaded ports, the VHP60 integrates securely into a wide range of professional and industrial cleaning setups, providing stable performance and peace of mind where system safety is critical.

Extreme-Duty Performance

The VHP 60 was developed for industries that demand continuous, high-pressure operation in some of the harshest working conditions. At nearly 9,000 PSI, the margin for error in pressure regulation is minimal. The VHP60 delivers instant bypass activation, redirecting water flow whenever the spray trigger is inactive. This prevents dangerous spikes, reduces stress on critical pump components, and extends the overall lifespan of the system.

From hydro blasting rigs used in paint and coating removal, to industrial degreasing lines in refineries and heavy plants, the VHP60 thrives under workloads that would quickly wear out standard unloaders. It is the kind of valve trusted by contractors and industrial crews where failure is not an option.

Built for Harsh Conditions

The VHP60 is manufactured using rugged, high-strength materials that can withstand not only extreme water pressures but also exposure to heat, vibration, and corrosive working environments. Whether mounted on a mobile rig or a stationary facility wash bay, this valve is designed to stay reliable even during long-duty cycles and heavy daily use.

By reinforcing both the housing and internal components, Annovi Reverberi has ensured that the VHP60 maintains consistent, leak-free regulation under the most punishing conditions. The precision-machined internals work in harmony with durable seals to provide both performance and reliability, minimizing service interruptions and reducing downtime costs.

Automatic Bypass for Safety

At its core, the VHP60 performs the critical function of an automatic bypass valve. The mechanism instantly diverts water whenever spray flow stops, protecting pumps from pressure overload. This action is not only critical for extending pump life but also essential for operator safety. By eliminating the risk of dangerous overpressure, the VHP60 makes sure cleaning crews can work with confidence, even under extreme-duty scenarios.

Applications Across Industries

The VHP60 is widely used across multiple industries where extreme pressures are required:

• Hydro blasting – Removal of coatings, rust, and industrial build-up from steel and concrete.
• Industrial degreasing – Heavy cleaning in refineries, manufacturing plants, and chemical facilities.
• Refinery maintenance – Safe, reliable performance in environments with flammable or corrosive substances.
• Contractor systems – High-pressure mobile rigs for construction, fleet maintenance, and heavy equipment cleaning.
• Marine applications – Effective for shipyard cleaning, hull preparation, and saltwater-exposed systems.

By covering such a wide range of environments, the VHP60 has become the go-to solution for professionals who cannot compromise on reliability or safety.
