AR51481 | VRP23 Pressure Regulator Pump Control Kit

AR51481 – Annovi Reverberi VRP23 Pressure Regulator | Pump Control Kit

Overview

The Annovi Reverberi AR51481 VRP23 Pressure Regulator is a professional-grade pump control assembly engineered to deliver accurate pressure management, stable flow regulation, and long-term system protection. Designed for industrial, commercial, and professional pressure washer systems, it maintains consistent water pressure under varying load conditions while preventing overpressure damage to pumps, hoses, and accessories.

Construction & Durability

• High-Strength Brass Body: Provides excellent resistance to pressure fatigue and corrosion.
• Stainless-Steel Internal Components: Includes spring, piston, and valve seat for smooth, corrosion-resistant operation.
• Precision-Machined Bore: Reduces friction and leakage to ensure stable pressure control.
• Chemical-Resistant Materials: Withstands exposure to harsh environments and cleaning chemicals.

Pressure Regulation & Bypass Function

• Automatic Pressure Control: Maintains set working pressure across variable loads.
• Integrated Bypass System: Diverts excess water flow when the spray gun trigger is released.
• Prevents Pump Damage: Eliminates deadheading by relieving pressure through the return circuit.
• Instant Restart Performance: Flow is redirected to full pressure immediately when the trigger is pulled again.

Adjustability & Performance

• Fine-Tune Regulating Knob: Allows precise output pressure adjustment for different applications.
• Wide Pressure Range: Supports low-pressure detergent application and full high-pressure washing.
• Balanced Piston Design: Responds instantly to pressure fluctuations for smooth and consistent spray output.
• Low-Turbulence Bypass Circuit: Reduces cavitation, hydraulic shock, and system vibration.

Internal Engineering Advantages

• Precision Sealing Surfaces: Ensure leak-free operation even at high pressures.
• Resilient Elastomer O-Rings: Provide long service intervals with minimal maintenance.
• Self-Lubricating Internals: Reduce wear and extend component life.
• Minimal Maintenance Design: Easy to service with modular components and no special tools required.

Compatibility & Installation
