SVL20/250 | Pressure Relief Valve 2900 PSI 66 GPM High Flow

SVL20/250 – Pressure Relief Valve – 2900 PSI – 66 GPM

Overview

The Annovi Reverberi SVL20/250 Pressure Relief Valve is a heavy-duty, high-capacity safety component engineered to protect pumps, piping, and accessories in large-scale water systems. Rated for 2,900 PSI and capable of handling flow rates up to 66 GPM, it is one of the most robust relief valves in AR’s lineup. Its primary function is to instantly release excess pressure that may develop within the system, preventing catastrophic failures and safeguarding critical infrastructure from costly damage.

Where smaller safety valves are sufficient for compact washers or residential units, the SVL20/250 is purpose-built for municipal utilities, agricultural irrigation, and industrial water applications where flow volumes are substantial and system reliability is critical.

Engineering & Construction

• Pressure Rating: 2,900 PSI maximum operating relief pressure.
• Flow Capacity: Supports up to 66 gallons per minute (GPM), making it suitable for high-volume systems.
• Inlet/Outlet Connections: Features a ¾″ female inlet and a 2″ outlet, designed to quickly expel excess water and stabilize operating pressure.
• Material: Built from corrosion-resistant alloys, ensuring durability in chemically aggressive or moisture-heavy environments.
• Design Philosophy: Oversized outlet diameter ensures fast pressure discharge, reducing the risk of pump cavitation or line rupture.

This valve is precision-machined to exacting tolerances, ensuring smooth spring action, accurate pressure response, and consistent resealing once system pressure stabilizes.

Functional Advantages

• Overpressure Protection: Automatically opens to release dangerous spikes, protecting pumps, fittings, and downstream components.
• High-Flow Performance: With its 66 GPM capacity, it is specifically designed for systems where large volumes of water must be managed safely.
• Pump & Hose Longevity: Reduces wear and tear by keeping system pressure within safe operating limits.
• System Reliability: Prevents downtime caused by ruptured hoses, blown seals, or damaged manifolds.
• Quick Recovery: Reseals smoothly once pressure returns to normal, maintaining uninterrupted system performance.

Installation & Maintenance Notes

Connection Points

• Inlet: ¾″ female thread for integration into pump or system manifolds.
• Outlet: 2″ discharge designed for rapid evacuation of excess flow.
• Orientation: Typically mounted on the discharge line or directly at the pump outlet to maximize protection.
• Serviceability: Minimal maintenance required beyond periodic inspections for debris, scale, or wear on seals.
• Calibration: Pre-set at the factory for safe operation. Field adjustments are not recommended, as this can compromise relief accuracy.
• Shipping & Availability: Stocked for UPS Ground shipping within 24 hours under standard conditions. During seasonal demand peaks, expect 2–3 business days processing.

Applications

The SVL20/250 excels in high-volume cleaning and water distribution systems where large flow rates and pressure stability are essential. Typical applications include:

• Municipal Systems: Protects pumps and pipelines in water distribution, fire suppression, and wastewater facilities.
• Agricultural Irrigation: Ensures stable operation of large irrigation pumps and distribution lines.
• Industrial Cleaning: Provides safety in high-volume wash bays, food processing plants, or fleet maintenance centers.
• Commercial Facilities: Safeguards equipment in factories, power plants, or chemical production environments.
• Marine & Shipyards: Protects pumps operating under continuous duty in saltwater or high-humidity conditions.
