SVL28 | Safety Relief Valve 4060 PSI Heavy-Duty Pump System

SVL28 Safety Relief Valve – Overview

• Compact, high-performance overpressure protection valve rated at 4,060 PSI
• Automatically releases excess pressure to protect pumps, hoses, and system components
• Engineered by Annovi Reverberi for industrial, commercial, and mobile cleaning systems
• Combines durable brass housing, stainless-steel internals, and precision calibration

Construction & Materials

Brass Housing

• Corrosion-resistant brass body ensures long service life
• Resists wear, water-induced corrosion, and pressure fluctuations
• Compact design integrates easily into pump manifolds and pressure washer systems

Stainless-Steel Internal Components

• Precision-machined piston and spring assembly for instant pressure response
• Hardened for exceptional wear resistance and long-term reliability
• Maintains accurate response across thousands of operating cycles

Elastomer Seals

• Chemical- and heat-resistant sealing compounds
• Retain flexibility under detergent and hot-water exposure
• Provide smooth resealing and leak-free performance

SVL28 Performance & Operation

Overpressure Protection

• Opens automatically at 4,060 PSI to vent excess fluid safely
• Prevents pump, hose, and fitting damage due to overloading
• Eliminates water hammer through smooth, controlled venting

Automatic Reset

• Valve reseats instantly once pressures return to safe levels
• Supports uninterrupted workflow with zero manual intervention
• Ideal for continuous-duty environments
