VHP50D | 8000 PSI Heavy-Duty High-Pressure Unloader Valve Unit

VHP50D – Unloader Valve – 8000 PSI

Overview

The Annovi Reverberi VHP50D is an extreme-duty unloader valve engineered specifically for seamless compatibility with Pressure Pro equipment. Rated for an ultra-high operating pressure of 8,000 PSI, it provides one of the highest levels of system protection available in the AR lineup—ideal for contractors, industrial facilities, and operators running high-demand cleaning systems.

As a core safety component, the VHP50D prevents overpressure spikes, stabilizes output, and extends pump life by diverting water into bypass whenever the spray trigger is released. Its advanced bypass mechanism ensures smooth, consistent, and instant pressure relief even under maximum load.

Engineered for Pressure Pro Equipment

The VHP50D is uniquely designed for Pressure Pro systems, with optimized dimensions, fittings, and internal flow paths. This eliminates common compatibility challenges and reduces the need for adapters or custom modifications.

• Exact fit for Pressure Pro configurations
• Faster installation with reduced setup complexity
• Reliable performance without retrofitting or rework

Extreme-Duty Performance – 8,000 PSI

With a maximum pressure rating of 8,000 PSI, the VHP50D is built for the most demanding environments and continuous-duty cycles. It maintains stable pressure and immediate bypass action through:

• Reinforced housing for sustained ultra-high-pressure operation
• Precision-machined internals for consistent regulation
• Automatic bypass activation to protect pumps, hoses, and nozzles

This level of protection prevents catastrophic failures and significantly increases the service life of pumps and high-pressure components.

VHP50D Built for Harsh Environments

Designed for extreme conditions, the VHP50D thrives in contractor rigs, industrial wash bays, and marine or offshore environments. Its rugged construction resists heat, vibration, corrosion, and continuous cycling.

• Durable under heavy daily use
• Stable performance across all duty cycles
• Lower maintenance requirements even in harsh environments
