Model B-3 Pilot Operated Pressure Regulating Valve

The Viking Model B-3 Pilot Operated Pressure Regulating Valve serves as a critical flow control component within industrial and commercial fire protection assemblies, specifically deployed to maintain precise downstream pressure regulation. Installed in wet sprinkler and suppression systems, this valve actively prevents pressure surges and safeguards sensitive downstream elements from fluctuating pressures that lead to leaks or system failure. By maintaining controlled pressure parameters, it ensures consistent operational reliability across your entire network.

This valve satisfies stringent national fire protection codes and regulatory mandates, strictly adhering to applicable NFPA standards for fire sprinkler installations. Compliance is further backed by mandatory industry certifications, ensuring facility managers and trade contractors meet strict life safety and code requirements for commercial properties.

• Ductile Iron Body: Crafted from high-strength ductile iron to provide exceptional resistance against mechanical stress and environmental corrosion in demanding industrial settings.
• Pilot-Operated Mechanism: Utilizes a reliable pilot system to actively regulate downstream pressure and block dangerous pressure spikes.
• Space-Efficient Design: Features a compact, streamlined footprint that allows for seamless integration into new mechanical room installations or tight retrofit projects.
• System Protection: Shields downstream piping and components from pressure fluctuations to reduce long-term maintenance costs and prevent catastrophic leaks.

Always verify local Authority Having Jurisdiction (AHJ) mandates and consult the manufacturer's engineering data sheets prior to beginning installation or system commissioning.
