VLP12-17 | Pressure Relief Valve 4060 PSI 3.2–4.5 GPM Range

VLP12-17 – Pressure Relief Valve – 4,060 PSI – 3.2–4.5 GPM

The Annovi Reverberi VLP12-17 is a medium-capacity pressure relief valve designed to provide dependable overpressure protection for residential, commercial, and light industrial pressure washing systems. With a working pressure rating of 4,060 PSI and a flow range of 3.2–4.5 GPM, this valve ensures safe, consistent system operation by automatically releasing excess water when dangerous pressure spikes occur. By preventing overpressure events, the VLP12-17 protects vital system components—pumps, hoses, guns, and fittings—prolonging their service life and minimizing costly downtime.

Why Pressure Relief Matters

During operation, a pressure washer pump is constantly generating force. If water flow is interrupted—whether by closing the trigger gun or a restriction in the line—pressure can build up rapidly. Without a relief valve, this buildup can exceed safe operating limits, leading to blown seals, cracked housings, hose ruptures, or pump failure.

The VLP12-17 is engineered to prevent those outcomes. It serves as a safety valve that automatically opens when system pressure exceeds its calibrated threshold, allowing water to bypass safely until normal conditions resume. This not only protects equipment but also improves operator safety by eliminating sudden surges that could result in hose whip or equipment damage.

Construction & Durability

The VLP12-17 is manufactured from corrosion-resistant materials, ensuring reliable operation even in environments with frequent exposure to water, detergents, or mild chemicals. Its robust housing and precision-machined internals are designed to withstand the rigors of daily use, whether on a residential driveway washer or a contractor’s commercial rig.

This valve’s durability translates directly into lower maintenance requirements and a longer service life, making it a cost-effective choice for operators who want dependable protection without constant service calls or part replacements.

Flow Range & Application Flexibility

With a flow capacity of 3.2–4.5 GPM, the VLP12-17 is tailored for medium-output systems. This makes it highly versatile, serving a broad spectrum of applications:

• Residential cleaning setups – pressure washers in the 3–4 GPM range benefit from reliable pump protection during daily use.
• Commercial contractors – mid-range washers used for siding, deck, and surface cleaning gain extended component life and reduced downtime.
• Facility maintenance crews – light commercial systems operating at moderate GPM levels receive dependable relief under variable workloads.

The flow range ensures the valve reacts consistently and efficiently without being oversized for compact systems or undersized for professional rigs in the mid-GPM class.

Ease of Integration

The VLP12-17 is designed for straightforward installation with standard plumbing interfaces. It can be added as a replacement valve during pump maintenance or integrated into new builds without requiring specialized tools or adapters. Operators benefit from plug-and-play reliability, ensuring their systems remain safe with minimal installation time.

Applications

The VLP12-17 is trusted by a wide variety of users who need safe, reliable protection for medium-capacity systems:

• Residential cleaning equipment – driveway and siding washers, patio cleaners, and home-maintenance rigs.
• Commercial contractors – mobile service professionals handling decks, fences, sidewalks, and mid-duty pressure cleaning.
• Facility maintenance teams – schools, municipalities, and businesses needing safe pump operation across daily tasks.
• Light industrial setups – workshops and service bays where compact pressure washers operate frequently under moderate workloads.
