2" 4000B RP Backflow Preventor Valve Heavy-Duty Ductile Iron Water Safety Valve

The 2" 4000B RP Backflow Preventor Valve is a heavy-duty water safety device designed for residential, commercial, and industrial plumbing or fire protection systems. Engineered from ductile iron and stainless steel components, this valve ensures reliable prevention of water contamination by effectively blocking backflow while maintaining flow efficiency.

• Durable Construction: The valve housing is crafted from ASTM A536 ductile iron, providing superior resistance to corrosion and mechanical stress for long-term use.
• Corrosion-Resistant Internals: Equipped with 300-series stainless steel springs and fasteners to protect against rust, extending service intervals without compromising performance.
• Advanced Sealing Technology: Utilizes high-strength thermoplastic check valves with EPDM elastomer seats that are reversible and replaceable, ensuring a secure shutoff and minimizing leakage risks.
• Regulatory Compliance: UL Listed per UL 312 for potable water, FM Approved for fire protection systems, and compliant with ASSE 1013 standards for backflow prevention reliability.
• Operational Range: Handles pressures up to 175 PSI and works efficiently within 33°F to 140°F, suitable for varied environments and typical indoor/outdoor installations.
• Versatile Installation: Features standard AWWA C606 grooved ends for quick connection and supports both horizontal and vertical installation with upward flow.
• Flow Efficiency: Incorporates a reduced pressure design to minimize pressure loss, improving overall water system efficiency compared to traditional backflow preventers.

This backflow preventer helps maintain the integrity of potable water systems by reliably stopping contaminated water from reversing into clean supply lines. Its heavy-duty materials and certifications make it an ideal choice for facility managers and contractors focused on compliance and safety in fire sprinkler and irrigation systems. The reversible valve seats simplify maintenance in locations where access is challenging, reducing downtime and service costs. Whether installed in a new setup or retrofitted into existing plumbing, the 4000B RP valve offers a durable, code-compliant solution that prioritizes water safety and system performance.
