The 4" 4000SSLG Reduced Pressure (RP) Backflow Preventer Valve is specifically designed for fire protection systems that demand uncompromised safety and reliability. Ideal for fire protection engineers, facility managers, and plumbing professionals, this valve prevents potable water contamination while ensuring efficient fire suppression system performance.

• Material Quality: Constructed from corrosion-resistant stainless steel alloy 4000SSLG, ensuring enhanced durability in harsh fire service environments.
• Valve Design: Reduced pressure zone mechanism effectively blocks backflow under both back-pressure and back-siphonage conditions.
• Seal Components: High-grade EPDM elastomer seats deliver a secure seal resistant to thermal cycling and chemical exposure, maintaining integrity over time.
• Pressure and Temperature Ratings: Operates reliably at pressures up to 175 PSI and temperature range from 33°F to 140°F, accommodating a variety of indoor and outdoor installation settings.
• Regulatory Compliance: Fully certified to UL 312, FM Approved, ASSE Standard 1013, and compliant with NFPA 13 and NFPA 25 standards, ensuring adherence to fire protection and plumbing codes.
• Connection Versatility: Compatible with ANSI B16.1 flanged or AWWA C606 grooved end connections, allowing seamless integration into diverse piping systems.
• Installation Flexibility: Supports horizontal and vertical (upward flow) mounting to fit different fire system layouts without compromising performance.

This backflow preventer valve safeguards potable water supplies by preventing hazardous backflow during fire events, which is critical for maintaining water quality and public health. Its stainless steel construction resists corrosion more effectively than typical brass or iron valves, reducing maintenance needs and extending service life, especially in demanding environments. Designed for commercial and industrial fire sprinkler systems, it balances robust protection with minimal pressure loss, ensuring that fire suppression systems perform reliably when needed. This valve is a practical choice for professionals requiring a dependable, code-compliant solution that minimizes contamination risks without sacrificing system efficiency.
